MPG problems following service
Discussion
Hoping someone can help me here. My car (Golf 1.4TSi 170) has just been in for its first service (last Wednesday) at approximately 17,000. Prior to the service, around town I would be getting about 36mpg. Motorway or decent A road, I would expect 40mpg, driving fairly conservatively.
From the moment I drove from the dealers the economy has plummeted. Around town I now get about 21mpg and if I am going as easy as possible on the motorway, I am lucky to see 30mpg. These figures are taken from the MFD; I haven’t done the brim to brim method, but then I never did before the service.
Has anyone else experienced / heard of this problem?
I am planning on contacting the dealer in question to ask if they have applied new software to the ECU. Is it common for them to apply new versions of the engine management software without informing the customer?
Cheers
