Faced interesting problem. 2 weeks ago, by brake fluide change in bleeding process kind of brake system pipe blow off-because " it was melted" as stated by bickerton, yesterday suddenly came big misfire (check engine lamp blinked several times, then constantly and then engine cuted off). Spark plug coils need to change- because contacts -melted?!

I'm not racing, temp gauge always on 90, no warning lights, no symptoms at all. Any ideas? Octavia vrs 2.0TFSI

Might be grounding, but should be over issues alongside (radio, car battery drain, lightning)!?

Try Grammar checking, maybe someone can then help. 

I think my Babel fish has seen better days!

I dont see how changing the brake fluid has caused a pipe to melt? i changed my brake fluid & it was a straight foward process. What year is your car as im sure there was a recall for the coils on the earlier cars. 

They are connected as much as melting plastic. Why its so hot under the bonnet- everything melts,-thats a million dollar question (actually 600£). The car is 2008.

So your saying when the dealer changed the brake fluid they found a melted pipe somewhere? & then you had the ignition coils fail? What pipe was it? it shouldnt be that hot under the bonnet that plastic is melting.

Exactly, and when I asked, why it happens, they said- they dont know. :/ Now car is stripped (not in dealer garage), but problem source still undetected-thats worry me a lot. :/

Sorted out, accidentally short circuit caused small melt down of spark plug coil contact alongside with piece of wiring. Reason-maybe bad contact, maybe disconnection. Outcome- changed spark plug coil and all wirring from the ecu.
