Another VW Sharan Misfire - Run out of ideas
My 1999 VW Sharan 110 bhp TDi (red i) has a misfire ('coughs' on acceleration). So far I have replaced/had tested the airmass meter; new injectors; new fuel filter; new battery; have had dismantled and tested the diesel fuel pump and as a last resort changed the fuel provider and used a fuel additive (the last being a suggestion of Honest John's).

I am loathe to part with the car as it goes well otherwise - is there anything left for me to try or will I be coughing all the way to the dealer via the bank for a replacement?

Another VW Sharan Misfire - jb
I\'ve only spotted this by chance. I had the same thing on a 1998 Sharan 1.9TDi Sport. When it misfired it was on all cylinders, normally when excelerating away from traffic lights/roundabouts, etc.. It was very momentary, but nevertheless quite alarming when it did it!

VW would NOT accept there was a problem. I fell out with a dealer in Birmingham and another in Worcester who actually accused me of lying! In 1999 I had the car for something like 4 weeks out of 6 months. The rest of the time it was \'in dock\'.

I had it independently checked - fortunately it was leased and the only way I finally made any headway with VW was using the might and buying power of Leasecontracts to help me. They never did find out what the problem was, but suspected a cracked block. Eventually, I (Leasecontracts) got VW to buy the car back.

A very unhappy saga for me, with the only consolation being it wasn\'t my money!

Good luck!
