Problem with 2002 Bora 2 Litre
Hi.
I'm new here and hoping someone can help me out with a major problem I am having with my Bora.
Over the last few months it has given us few subtle problems.
It began with struggling to start up every now and again. I put it down to battery but had it checked and was assured the battery was ok.
this struggle to start up has escalated to severe acceleration problems. I noticed that my take offs (which used to be fantastic!) started to lack luster. I had the services etc done in due course. It only has about 70,000 ks on it. So it's a well looked after family car, which was always very reliable and a pleasure to drive.
Over the last month it has been struggling to go. It feels like there is no fuel going through and it wants to stall.
We have had the fuel system flushed and serviced- no change.
We then had the mobile mechanics come out (due to the VW "service" centre sounding like they were ready to rob me blind to even diagnose it).
The mechanic who came out did the diagnostic on it and it brought up 2 errors. 1- the ECTS (engine coolant temperature sensor) and 2- Cylinder 2 misfire. The guy assured us that changing one may delete both errors. He recommended changing the ECTS, which we did that day (he told us it was easy to do and my father who is an old mechanic did it with no problems).
We changed all the spark plugs the same day also. He assured us that we wouldn't see a change in the car immediately.. so we have been patiently driving it about but it's getting worse.
We had it connected to that diagnostic machine again today and it is now bringing up NO errors.
No take offs, particular jerking and struggling to move (even if you're flooring the accelerator) between 55-100kms.
It has become extremely unreliable and we are at a loss as to where to go next and what to do.
We are in Melbourne, so if anyone can suggest our next step we would really appreciate it as we are at a loss and we don't want to get rid of the car. It was always such a great drive.
Thanks in advance!

We're in the Taylors Lakes area. Do you have any ideas what it might be?Originally Posted by FknDubbin

Holy crap. I live in Camberwell. Fair drive. Will you be going to Day Of the Volkswagen on Sunday? If so, i can have a squiz at it there.

Mate here is my feed back disconnect your airflow meter and try driving it with it disconnected, disconnected by means of pulling the plug off only. You will store a fault by doing this but if it runs better then just erase it after you fit the new part. Did the guy checking with VAG COm watch the (faulty coolant sensor) with the live data stream? Not all faults that show up mean that its that particular sensor, sometimes its actually doing its job properly and is just having to operate past its parameters.
C how you go

Yeah i forgot about a dead MAF. We were replacing them heaps at VW.

my old 2.0L golf had the same problem,
we fixed it by replacing the MAF sensor and o2 sensors.

It could also be a vacum leak on your intake somewhere and the air is not going past the MAF causing the motor to go into limp mode. Check all of your clamps and look for any holes.
Disconecting the MAF will also prove if this could be a potential problem. The car will still run ok without the MAF. This is just a cheaper sugestion to try first before repacing.
Thanks for the responses.
Just to clarify (please excuse my ignorance) but if I disconnect the MAF and drive it, can it potentially create more damage elsewhere?
I guess what I'm asking is, how long should I be driving with the MAF disconnected before becoming concerned about further damage?
The problem is intimitant and we can't seem to reproduce it on demand, so we may need to drive around for a while to be sure.
no he didn't. He was only watching for the reappearance of the error codes.

You can drive for ages with the MAF disconnected if you need too. It won't run perfectly but it'll prove it's good or bad. You can see the live data for it in measuring blocks with VAG-COM.
The ECU is programmed to ignore a bad output from the MAF in the event of it failing or being disconnected.
MAFs very rarely throw a code you just end up seeing symptoms of them not working correctly.
