Hi Lofty
Just joined this forum so that I can add my views on your thread. I have a 2002 SEAT Leon tdi 90bhp (although according to my friendly SEAT expert it has a 115bhp remap).
For the last year it has been gutless to the point of being dangerous to try and overtake anything.
Followed all your instructions for the Mr Muscle treatment and whilst at it, cleaned the EGR valve. It was hopelessly blocked with S*** and corruption. Took it out for a spin and…………….wait for it………………………no real difference.
I felt a bit fed up but not dejected because I can understand the logic and the chemistry of what the thread is all about. Late yesterday as darkness fell (no garage to work in) I rang a mechanic friend who happens to be an ex-SEAT mechanic (didnt know that when I rang him). He collected the car and immediately diagnosed the fault as a faulty barometric sensor. By 11am today it was replaced and the readings on his plug in computer said everything was pretty much right. However I felt that there was still a possible vacuum leak as I had damaged the vacuum sensor connector on the one way valve from the vac pump to the brake servo. This was replaced. Once this was done the turbo pushed out smoke and crud. I have just taken it for a spin prior to a 300 mike trip tomorrow. The car is unrecognisable. It pulls better than it ever has done in 2 years of ownership and the mechanic told me that it is going so well that the turbo and EGR have to be spot on for this type of performance. So, although I had to wait a little longer than some, thanks to you I now have a car that is far better than the day I bought it.
If it gets better after a decent thrash tomorrow I will let you know. My thoughts on the remap by the way are that this was probably done in an attempt to improve the flagging performance. So for all the potential remap customers out there, it makes clear sense to clean the vanes and the egr before doing anything else.
Thanks again Lofty!!
By the way, I was all for selling the Leon; but not now so looking for some better seats. I have been told that Octavia seats fit the Leon. Is this right? If so please contact me if you have any that are comfortable and a bit more supportive than basic SEAT seats. Pref grey cloth or black leather. Car is red with grey interior.
