Hi folks,
Two weeks ago I took my car for a drive to try to unblock the antipollution filter. As I didn't have time to take it on a motorway I decided to drive the car in third gear with a speed between 50 - 60 mph. After approximately 20 minutes the filter light went out. Moments later the revs rapidly gained accompanied by thick smoke and I quickly managed to slow the car and the revs dropped almost as quickly. A check engine message then appeared so I pulled over a few minutes later in a layby and was able to turn the car off. I restarted the car and drove home cautiously but found the turbo to be functioning okay. The car running quite rough though.
A couple of days later I took the car into my local garage (not Fiat) to be looked at. The fuel jets were tested and the parameters from the live data were the same found by Fiat for number 4 as when I previously had a fault with the same jet last year. The car was under warranty (not with Fiat) and the number 4 jet was replaced.
I took the car back to the garage (the car taking a while to start, occasional plumes of thick white smoke appearing from the back of the car until it had warmed up and was still running rough) and told them that a fault had been diagnosed by another garage and that the fuel jet they had supplied wasn't functioning properly. The warranty garage tested the jets and claimed that the number 4 jet was working correctly.
I then told them what had happened when I had driven the car and when another "test" was done they found that there is low compression on cylinder 4 but gave no suggestion as to why.
I decided to leave the car with them assuming that they would try to fit the car in and after three days of them having the car and me being fobbed off over the phone they still haven't diagnosed the problem. As I am a driving instructor not having a useable car for two weeks is obviously not a great situation! I think Monday if they're not going to spend any serious time on the car I will drive it back to my local garage LMC in Pulborough as they do the job well!
Anyway has anybody come across this before or have any suggestions?
Cheers!
