in my experience (and i dealt with these muppetts loads) they will do the basics they need to do to get paid , ie change ecu ect , when you talk to them on a mechanical basis they know f*uk all about anything.
my dealer told me that a noise on my car was how a cupra should sound and he had comparred it to another cupra they had in for a service so down i went compared the 2 cars and guess what no noise on the other car.
most of what they say is because they know they cant justify the labour costs back from SEAT so you get fobbed off.
Customers and owners are not listened to because sometimes we inconvience them by turning up with a fault that doesnt always show up on their computer.
I went out on a test drive with my local master tech for a noise missfire that occured at 50 mph in 6th
gave him precise instructions change into 6th at 50 or roughly 3,000 rpm ,
we pulled out of the car park and the fecker started to drive it like he had stolen it !
hang on a inuete i said , its ok these engines like to be driven hard !
guess what couldnt replicate the
problem until i drove it !
their total attitude stinks.
