1.9tdi Polo repair suggestions.

[Docharding]

Hi all

I need some advice, I have a 2006 1.9tdi Polo that is nearly on 200000km and I want to spend a bit of money on getting things done. So what I would like to know what are the common issues I should think of doing now before they become a problem. There are no problems at the moment, touch wood, however I'm thinking about just doing the whole suspension, CV's, bearings etc any advice would greatly appreciated

Don't fix stuff that is not "broken"... leave the bearings, they are a pain to replace and quite expensive if you get OEM ones.
CVs, same story, if they are noisy yes replace but mine is at 328500km on original CVs, CV boots and bearings.

Suspension, look at Lower Control Arm bushes and shocks if they haven't been replaced before. You can get decent Bilsteins from Goldwagen for a good price.

Check your intercooler, it might be leaking. You will see a lot of dirt and oil on it if it does.

Your alternator pulley will fail at some stage, replace that, the tensioner and belt.

Save the rest of the money for turbo, injectors and tandem pump in case they give issues.

Your car is just on another level in terms of being reliable, it just never cease to amaze me.

It all depends. Issues are not always dependent on mileage or age. Do the shocks and control arm bushes as those are probably worn and rather just put some money away for any other maintenance that you might need down the road.

As vgti mentioned. Dont fix that is not broken. Just do your normal services and major service when due. The suspension components can be checked and replaced only when needed or worn. Check brake disc and pads while you at it.

Looking at your mileage your major(cam-belt,tensioner's water pump) is due if not done already.

Otherwise as others have said, don't fix whats not broken.

If never done previously, I would do a sump service just to be sure the pickup is nice and clean

Hey gentlemen,

I've got abit of a problem, My car recently made this strange noise upon idle and light acceleration on the right hand side of the engine, like a bearing/belt noise I've done some research and thing it could be a possible alternator pulley that has went but before i place the car under the knife i just would like to know if it a possible problem, the cars alternator pulley has never been replaced to my knowledge and i am sitting on 346 000 on the ODO

Cambelt and tensioner was done 3 months back.

This noise is just really annoying as I'm OCD to strange noises on my car



any advice would be appreciated


Thanks Chaps

Yes most likely your alternator pulley (one way bearing). Mine jumped off at around 270000km.... literally... landed on the chassis leg with the belt.

The pulley is a bit pricey but available at Goldwagen or Diesel Electric and you will need the necesary spline tool to take it off. Replace the belt tensioner and belt at the same time.

I have the spline tool at home somewhere but will have to look for it, you are welcome to borrow it

Shot!

Will try and replace ASAP dont want any nasty things happening to my beloved lol

Thanks for the offer boet but ive got that laying around, Just wondering how much will it cost *Thinking* currently running a 1.4 BLM motor

Went to my mac and Diagnosed the strange noise on the right side of the engine as a falling water pump and not a alternator pulley as the noise seems to becoming from underneath the tensioner

Hopefully I can get it sorted this week and avoid driving the car at all

You might as well have done the water pump too. My brother's Xpolo is on 290k km, and water pump was always done at cambelt (even though pump that was removed looked new still)

ps: has the water pump ever been replaced on yours?

[Wolfburger]

Yeah I should have now I know for next time

Yes it was last replaced at 135 000 according to the service books so this current one has a good 7 years to it's name.

It can also be the bearing on the tensioner.

Shouldn't some preventative maintenance be done on the injectors, have them tested etc?

Is the 1.9tdi engine relatively bulletproof, is it the same basic power plant as on the golf and A4 of those years?

Purging injectors at every service or every second service is some sort of preventative maint..

In my knowledge all 4cyl PD engines are the same. Turbos and injectors are the only differences between them (74kw, 96kw and the boss is the cupra i think 118kw).
Some stuff such as the intake and exh manifolds, etc are different from longitudinal on the audis than on the transverse on the polos and golfs.. otherwise they basically the same.
