I couldnt agree with you more. My last outing to my Local VW Cali dealer left me less than satisfied. They can sell them to you but I am afraid to say the struggle to fix them.
It hurts me to say, but they are just not engineers/Mechanic's anymore. If the computer say's "no", you've had it.
My last service was a joke, I almost laughed when they provided me the cost. It's not the money (these are not cheap units after all), it's the quality of it.
Simple things like managing to pour about half a litre of oild down the back of the block, most of the pipework and onto the exhaust. Made it smell like a Diesel tug boat on the trip back home!!
My recent fun and games with the aux heater left me no more confident.
One dealer ship came back after one hour saying it had a fault and could not turn it on (I handed this info onto the supposed cheif tech when I drove in!!) and that resolution may be a new head up unit (£560) but as the had no stock, they could not prove it to be the answer and that I would have to pay for the unit, if it fixed it or not!!?
The second closest dealer reasured me they could resolve it and then blew it all by saying that it was too warn now anyway and would not work. I explained to him he was talking about the pre-heater and I the Air-top. He than stated that they were both the same...I went on to explain that one heated water and one air.
Needless to say, it didnt go in there either.
Seems to me that the techs dont have specific training on Cali's just van and maybe then, only based around fault codes. I'm sure there are good ones but I've not found them yet.
Oh, as a side job, I build and restore classic race and rally cars for customers, and have done for around 20 years, more in the last 10.
The reason the Cali went into VW for it's last service was it was near on the same for me to buy the oils and filters than for them to do it!! Made sense...then.
Anyway...If you do go for the Fiamma aftermarket one. It takes about 1 hour to fit and is really easy. Two man job to lift the actual unit onto the brackets, that's all.
Rant over!!
