What to look for when buying high mileage 1.9TDI?
I'm going to look at a 2002 Audi A4 Avant 1.9TDI Manual 220,000km on the clock, been looking for a Golf Estate but there are not many around
What must I look out for to prevent buying a lemon?
Potential pitfalls of these older A4 avants/1.9TDI engines?
Luckily it's a manual so hopefully no expensive gearbox issues but are the manual boxes in these vehicles relatively hassle free?

Re: What to look for when buying high mileage 1.9TDI?
220k is hardly high mileage for a tdi. The best is to go there with VCDS to scan and do a quick log. If that's not possible, I would ask that the owner let you cold start the car. Check for signs of recent, major engine work (i.e if the head gasket tab on the front of the motor looks new, etc. Check for turbo whining, white smoke, black smoke, an uneven idle, tappety motor sound. Check the long term fuel consumption on the display.

Thanks THANAS, I don't have a VCDS currently but I may be able to borrow one, will that be able to show a history of the fault codes?THANAS wrote:220k is hardly high mileage for a tdi.

How do you check the long term fuel consumption, scroll through the dashboard display info and one will be the long term consumption?
Apart from running through the gears and doing a road test what can I check on the gearbox, noises to listen for?

Re: What to look for when buying high mileage 1.9TDI?
U wont be able to check the fault history on that specific car.. u can check for any existing fault codes though, mileage rewinding is also common - vcds can check true mileage.
U can also kind of tell condition of injectors from vcds.
Gearboxes seem quite strong on them, u can listen for whining while driving, or the common dmf issue - a rattle that goes away when the clutch pedal is pressed. U can also check for clutch slippage (go WOT from a lower speed in a low gear (be reasonable when doing this)
These are about the most costly stuff that can go wrong (also what thanas has advised regarding smoke, turbo, etc). Also check if the car has a service history and what type of oil was being used - proper spec of oil is very important on these engines.

Re: What to look for when buying high mileage 1.9TDI?
Thanks Ashveer, appreciate the info.
At 220,000km what kind of work should have been done recently or what will be coming up soon?
Diesel still uses timing chains etc?
How much parts crossover is there between the Audi and VW 1.9tdi and does Goldwagen carry a fair amount of the spares?

Re: What to look for when buying high mileage 1.9TDI?
Cambelt should have been done at 180k kms.
Personally, i dont trust anybody. If i was in your situation, i would replace the cambelt kit with a service irrespective of the mileage. (Thats just me though..) A service with a cambelt kit parts only cost around R3k
A clutch should be quite worn out at 200k kms, depends on how the previous owner has driven it. If theres no slipping or dmf rattle then u should be good for now. A new clutch kit ranges from R5-9k depending on the make and whether is a dual mass or single mass kit.
Again, if the incorrect oil has been used then the cam assembly should have some wear. Its not a problem unless the car has drivability issues (misfiring, tappet noises, unstable idle, etc). A cam kit costs around R5-6k parts only.
If the car is stock, i would also remove the catalytic converter and clean up the egr and intake manifold. Maybe even drain out the oil from the intercooler.
I assume the car has a PD engine, the only chain it has is from the crank to oil pump. Otherwise its belt driven.
As Thanas also mentioned about smoke and turbo whining etc, all this stuff really depends on how the vehicle has been used as there is no specific time that the turbo/injectors/piston rings, etc must be reconditioned or replaced. So u take it as it comes (u can check for wear on these parts though so u have an idea on what will need to be done). 220k kms on a diesel engine is no issue, they can take much more it just depends on how its driven and maintained.
If the car has a pd engine, then yea most of the pd engine stuff is interchangable. There are a few differences on certain stuff between the longitudinal (on audi) and transverse engines (polo, golf), like the intake and exhaust manifolds, boost piping, etc is different.
And yes, goldwagon stocks most if not all parts for these cars.

Re: What to look for when buying high mileage 1.9TDI?
Went and looked at it just now, nice body, interior not terrible considering the age(apart from that velvet touch coating that goes south on all older vag vehicles) but aircon is not working, apparently the compressor is toast and will cost R15k+ to repair
It wasn't totally cold on start up, made a small amount of black smoke but when the guy was moving the car out of the parking area it made a fair amount of blue smoke, what would that indicate?
Apparently the turbo was replaced recently, guy is asking R55k, probably too much even if the aircon wasn't broken, especially seeing it's the Avant/old/higher mileage.
I took it for a spin, man that engine pulls when the turbo kicks in! Very surprised, would be a fun car to drive, nice smooth clutch.

Walk away, I wouldn't buy a car without working aircon unless it never came with it in the first place. Plenty good TDIS out there.

Re: What to look for when buying high mileage 1.9TDI?
But I'm mighty impressed with the acceleration on the 1.9tdi, especially on a big car like an A4 stationwagon it pulled like a sports car and it seemed like it had legs, I was in a residential area so couldn't really test it but to my mind best of both worlds, apparently very good economy and a bit of gas when you need it.
The polo 1.9tdi with such a small body must shunt?!

It must be seriously nippy with mods. What advantages would your modded 1.9 diesel have over the the stock polo gti petrol, more low down grunt?Ashveer03 wrote:I have a polo 1.9tdi sportline, pretty nippy when stock, more like a demon when modified.. lol

Re: What to look for when buying high mileage 1.9TDI?
Im sure i would smoke a stock polo gti.. with the stock turbo and stage2 i could run away from a stock manual golf 5 gti
Regarding the torque, it has loads of torque low down (i havnt dyno'd yet - still running in a new clutch but it should be between 400-500nm)

Re: What to look for when buying high mileage 1.9TDI?
Guys, my problem is that when driving over 140-160, the car starts to over heat. Months back, I was involved in accident and everything was repaired. On a steep incline, it gets quicker to over heat. Golf 5 1.9 tdi.
What could be the problem?.

Re: What to look for when buying high mileage 1.9TDI?
man how much i love mine!
but blue or white smoke could be injectors, which are 7-9 k each, can be refurbed / swopped for 3k each
4.4l per 100km is my consumption calculated when filling at the pump, obc says 4.2
over 1750km on a tank everytime with still over 7l left in reserve! (85l tank)
b6 1.9tdi common faults:
Plenum Chamber Grommets - have not experienced this
-Plenum Chamber grommets block with silt allowing water to fill the plenum chamber infront of the windscreen. Causes flooding into passenger footwell, ECU, HVAC fan, brake servo.
-Remove grommets by removing battery and battery tray.
Wiper mechanism seizing - have not experienced this
-The mechanism that links the motor to the wiper arms can seize up
-Remove mechanism and regrease all moving parts
Air con regas - have not experienced this, but could be colder
-Airconditioning system slowly leaks and requires regular regas. Pump fails to operate below a certain gas pressure.
-Regas every couple of years.
Brake Light Switch - have had this happen once
-Traction control light comes on when brake pedal is first pressed
-Replace Brake light Switch
Airbag connector below seat - have this fault on front passenger seat, i clear with vcds and have found a good seat position
-Airbag connectors below driver or passenger seat cause airbag light to come on
-Clean connector and add switch lubricant to connections
Speakers crackling - i have this happens for a split second or so
-Door connections for speaker wires were manufactured with grease in the terminals which breaks down and causes speakers to fail & crackle
-Remove grease from door connectors
Rear washer jets block - think mine is blocked, but i dont use rear wipe as is sits skew after use and is a mission to get aligned!
-Rear washer jets block causing washer pipe failure and corrosion within tailgate
-Keep jets clean
Glovebox hinges - have not experienced this
-The soft close damper/ glovebox light switch unit becomes stiff putting unnecessary stress on the glovebox hinges
-Remove plastic cover on the side of the glovebox and lubricate light switch plunger
Worn fuel line - this i can see how it happens, but i dont have the issue as mine is sitting correct
-On 1.9 TDI -The fuel line rubs on the underside of the air intake pipe that goes into the EGR valve. Wear occurs because braided protection slides further down the fuel line exposing the rubber.
-Reposition braided protection on fuel line and secure with zip tie/ jubilee clip
HVAC failure - i have this issue show up in vcds, but i cant say it affects anything, i clear with vcds and re-calibrate every no and then
-There are small servos that control the HVAC system which are prone to failure. Motors show signs of failure when the start to 'click'. Defroster flap commonly first to fail. Remove glovebox to access 4 servos including defroster flap.
-Replace servo or disconnect whilst open.
Coolant Temperature Sensor
-Prone to failure and throw an intermittent fault code
-Replace coolant sensor
Thermostat - mine was stuck open and car was never reaching temp, replaced with cambelt service and gets to 90 in 10min and stays there!
-Prone to fail overtime and engine can no longer remain at 90 degrees during use. Engine takes a long time to warm up.
-Replace thermostat
Battery failure - have not experienced this
-First signs of the battery failing is a brake warning light on the DIS followed by 3 beeps. First occurs during cold weather. A good battery should hold 12.6v, weak battery will be 12.2v or less.
-Replace battery
Rear Anti roll bars - have not experienced this
-Anti roll bars corrode, crack the plastic collar which then damages the rubber bush.
-Replace anti roll bar and rubber bushes
Wiper blades - have not experienced this but i do know you have to buy proper audi blades and not just any generic, but i made a plan and fitted generic ones
-Clips securing the wiper blade to the arm break. Also plastic hinge piece prone to wear allowing deflector blade to touch & scratch the windscreen.
-Replace entire wiper arm as clips are not available separately.
another issue is suspension creak which i have when turning, apparently the anti roll bars need greasing to could be shock top mounts
think thats about it!

Re: What to look for when buying high mileage 1.9TDI?
Thanks Jueshen, that's some awesome info, your fuel economy is amazing.
The 2hnd TDI seems to be the best value with the A4, cheap to pick them up once a bit past 10yrs old, reliable and great economy for such a big car and a bit of performance when needed.
Is yours a B6 or newer version?
The 1.9 TDI has been around for donkeys years now, how has it been uprated and modified over the years?

Re: What to look for when buying high mileage 1.9TDI?
What is a Audi Avant 2004 model 1.9 tdi 6 speed 96KW like?
I'm going to see it tomorrow, everything checks out thus far but the owner says it has slight engine vibration at idle but that the vibration goes away at speed, he says its the one engine mounting needs replacing - does that sound about right?
Could an engine vibration at idle perhaps be something more serious?
Is there anything in general I should be looking out for when I go view it?
At start there should be at most a small amount of black smoke and no white or blue smoke otherwise?
Does anyone perhaps know a mechanic near Epping in Capetown that I can take the vehicle to for a quick check-up and confirmation on the engine mounting?
I got a lift from George to CT tomorrow morning and I'm driving down specially to have a look at it!!

Mountings are really not a common thing on this car, i have worked on a good few audi tdis with over 200k kms and never ever had a mounting issue. Its probably a dual mass flywheel vibration/rattle, which should fade off with the clutch pressed in as explained in the earlier posts. It could be a number of other things aswell, a misfire or maybe even a bashed up exhaust for example, very difficult "guessing".
A broken mounting should be quite noticeable though, if the engine has alot of movement when being revved up a little, or while driving - during gear changes..
Blue or white smoke is not acceptable.

When a car tailgates me, i slow down - then floor it and give them a cloud of diesel smoke to choke on

Re: What to look for when buying high mileage 1.9TDI?
Thanks Ashveer, seems another common issue with idle vibrations is the timing not being set properly after changing the cambelt?
Ideally should there be no white or blue smoke whatsoever or is a little bit of either at certain times passable?
