JohnR Posted January 25, 2007 Report Posted January 25, 2007 My booster heater worked fine after changing the glowplug about 3 months back, but has just started shutting down about 1 minute after firing up. Vag-com says "over temperature sensor". The dealers want Quote
NikpV Posted January 25, 2007 Report Posted January 25, 2007 we had 'jaroth' a sertvice engineer for these heaters register a few months back and I did ask him for you IIRC you had the errors but it worked fine - can't remember if he answered - serach for his posts and maybe pm him ?? Quote
JohnR Posted January 25, 2007 Author Report Posted January 25, 2007 Thanks....just referred back. Yes, it was giving the same warning message then, but seemed to still work. It now shuts down after a minute as I said, and after a few days of 1 minute fire-ups gives "function locked out" until you squirt it with the vag-com again. Have pm'd Jaroth as suggested. Am thinking that I'll bypass the heater with a piece of copper pipe and do a proper strip and rebuild this time. Should have done it properly last time while the weather was warm! John Quote
gazza007 Posted January 25, 2007 Report Posted January 25, 2007 Make sure that your run-on pump is working as this was causing my booster to start-stop as water wasn't circulating properly & system reporting as too hot. run-on thread Quote
JohnR Posted January 25, 2007 Author Report Posted January 25, 2007 I just read the thread....its possible. Mines done 97k and 4 yrs old. Whats the easiest way to see if the run-on pump is working? John Quote
