Hi,
I have a 2001 model Passat 1.9 TDi Sport with 130K. I got a the ECU remapped last summer.
I noticed a few months ago I was losing coolant. No visible leak and it was'nt losing it from the exhaust either. Was not overheating or building pressure in the radiator pipes. There was no oil/water mixture either. Got worse recently and I had to refill the tank once a week. (I do about 500 miles a week). Changed the coolant cap as I know these go after a while. No luck. Then I was told the water pump was leaking so a timing belt change was due and I got water pump changed and new radiator (which I was told was weak).
Still had the same problem so I was told it may be a dodgy thermostat which I had changed. Since then the car has started to build pressure in both the pipes that come out of the radiator and I can see the water leaking now from the overflow on the coolant tank. Now the mechanic tells me that the headgasket is blown and its all down the ECU remapp I had done.
Has anyone had a similair experience i.e. remapped ecu and had problem with the headgasket? Appreciate your thoughts / comments.
Thanks
