Firstly I can't believe there are no webasto recognised engineers on their website in Swindon.
My heater brought just over 2 years ago. (Jan 2011) has gone kaput.
Took it to Bristol auto electrical last Monday, new burner unit required, so they stripped it out last week and now I'm back having it installed.
Gonna cost the best part of £400 I reckon including parts and labour.
I will not be going down the diesel heated system route ever again, after reading Lee Priors posts that he had 2 shower heaters with gas supplied and fitted for around £300 each.
What a bloody rip off these systems are. £2500 2 years ago, I expected to last me at least 5 years.
Not a happy bunny, rant over
