Map sensor
Good day Everyone
I have been experiencing a problem with my car in relation to engine power. Its a VW Golf 1.4 Citi sport, fuel injection.
Firstly the take off speed of the car is just not the same, on inclines i experience engine power loss...i can hardly reach 140km/h with the car its even a problem trying to overtake,
and also the petrol consumption is just too much. Lastly wen i start the car in the morning there's a bit of white smoke that comes but then it stops.
So i was suspecting the Map sensor because the car is just not going anywhere, i don't know if i'm right tho...your help and views will be highly appreciated.

Re: Map sensor
Get somebody experienced to have it checked out, if im not mistaken the citi sport is mpi, and u could be experiencing the dreaded mpi ecu issue. There are a few threads of the symptoms of a faulty mpi ecu, read through them and check if u have similar symptoms

Re: Map sensor
I changed my map sensor, still there is no change, i also did my timing again but car still has no power.@ Ashveer03 , i think its best to let someone experienced check it out, because most people i have went to cant seem to find the problem.

Re: Map sensor
Ah 2009 was the intro year of MPI. Have the timing set on a dyno for best power and get somebodybto scanit with vcds. If it tells you lambda sensor open or short circuit then I have bad news for you.

Re: Map sensor
What would the lambda sensor open or short circuit mean Panic? I am also experiencing this issue on my 2009 Rox 1.4i
How does one go about working around the MPI issue?

Re: Map sensor
Hi Panic / All,
I get the following Lambda DTC's on 2008 Tenaciti 1.4i
Does this also point in the faulty ECU direction or can this be resolved without replacing the ECU?
Also, where exactly is the o2 sensor and Lamda sensor located on the car?

Re: Map sensor
Knock yourself out. It sits under the car. Most exhaust shops would be able to help you fit it chop chop. Clear the fault and see.

Re: Map sensor
I have the same problem on a 2003 Golf mk4 with 1.6SR motor. Its lost mega power over the years can barely go uphill. Also changed MAP sensor and no fix.
Where is a good place to find aftermarket ECU and not break the bank?

Re: Map sensor
Mk4 had a very different motronic unit and basically nothing related to the city issue will apply there.
On those start by replacing the lambda sensor and see that it receives power. Don't assume that what applies to one car does automatically to another.
This issue is MPI specific. Basically only found on the citi golfs.

Re: Map sensor
There's no MAP sensor on a Mk4 1.6, just a MAF. Dicktator 60-2 or something similar will maybe be in the region of R6k fitted and tuned.

Thanks for the advice. Apologies to You the OP if I hijacked the thread slightly.panic-mechanic wrote: ↑Fri Mar 29, 2019 9:25 am Mk4 had a very different motronic unit and basically nothing related to the city issue will apply there.

Re: Map sensor
Original thread is 2 years old and the OP has not visited since.....
your car could have lost power for many other reasons than blaming the management. You could very likely put something else on and have the same exact issue. Have you ever scanned or had is scanned to see if it complains about something ?.

Re: Map sensor
Yeah the last diagnostic I had done said MAF sensor and something about Catalytic convertor I think. I am going to have the CAT removed soon and see if that also helps. Im told they can cause performance issues over time but that remains to be factually confirmed.....panic-mechanic wrote: ↑Fri Mar 29, 2019 10:45 am Original thread is 2 years old and the OP has not visited since.....

Re: Map sensor
A dead maf sensor will certainly make it lazy. Yes cats can and do get blocked up over time specially if it was driven softly all it's life.

Re: Map sensor
Panic,
My messages getting stuck in outbox. I would like to bring my car for timing and tuning if possible. CAM belt whining (like its fitted too tight) and timing seems off. Please let me know how best to contact you .
