I would like to offer my sincerest thanks & gratitude to FRENCHMIKE for sharing his knowledge on fixing the Webasto. I have a BMW X5 & as a result of following his diagnosis & repair procedure I successfully repaired mine today.
Well done FRENCHMIKE & a big round of applause to you! Thank you so much. |

I have a 2005 E53 with a erratic running combustion fan motor. It will start OK run for about 2 minutes then run erratically & shut down with INPA message Fan interruption. Have read about faulty 4.7k resistors in PCB but could it be clogged combustion chamber causing flame out? Can you repair BMW PCD's. I am capable of changing resistors but don't want to start until sure that fault is PCB? Would appreciate your thoughts Mark A |

Hi Mark,
You have to know that i can't test entirely the BMW one's for the cycle is depending on the Kbus 'car. I only can test the driving of the external components .and read the recorded errors. The Rover's are more easy to test .. However,i can still have a look Mike |

Hi, and happy new year to everyone. My first post after being a member for ages, apart from P.Ming big russ and having him remap 2 ecu's. I don't really want to impose on the good people here, but I feel I need some answers from the boffins here! I have ploughed through endless threads and posts, but just got mesmerised, so I hope it's ok to post here!
I have a unhealthy obsession with fbh's, especially after reading the endless information on this site about them, and past experience with cab heaters in my trucks! I have one already fitted to my saloon, but I bought one complete with pump, and retro- fitted it to my 52 plate tourer. As soon as I put fuse 8 in, the fan motor burst into life and ran a few seconds. I couldn't get it to run at all after that, it was dead, tried resetting it by removing the fuse, but still nothing on earthing pin 6. I replaced the fuse a day or so later and it fired up and ran! I was a happy chappy! However, after a week it just started running the fan and the water pump, but it just wouldn't fire. I tried resetting again, but nothing. I have a perfectly good one, which I know works on my 75 saloon, swapped them round, it did the same thing when connecting the battery to the saloon, only this time it burst into life, only to cut out and just run the fan, blowing cold air out of the exhaust and circulating water. Fired up the known good one on the tourer (originally off the saloon) and it worked perfectly!!..... For a week.... Now, Monday, that one has started the same game!! Although, this one doesn't start running on connecting the fuse, symptoms are the same, i.e. running the fan (a little faster than usual) and water pump, but not firing!I also bought 2 gsm's off ebay after reading all about them on here, but they aren't without their faults either!! one doesn't quite work as it should, although, i have no instructions apart from what's on the listing and what i can squeeze out of the guy by asking! and the other didn't work at all!!!!I also fitted the maplin relay on the heater too, as done by another excellent life-saving-member, it was lovely while i had it all working "to a fashion"! Now, someone mentioned that they aren't very good as anchors or doorstops, but I'm liking the idea of donning my steel toe cap boots and launching them like rugby balls, or, a splash of petrol and a match to activate them....I hope the other genius aka FrenchMike reads this, because, surely it would be an unlikely coincidence that both pcb's fail, and in the same way in such a short time? unless it's something that is blowing the resistors, but there's only the 5c temp wire, dosing pump and pin 6 earth activator fitted, the k-bus is disconnected.On another note, i removed the first pcb, cleaned off the gum around the capacitors and found the furthest right one was black on where it had sat on the resistors I also took out the pcb for the other fbh, but surprisingly, this one is almost charred under the blob of gum,on the right of the pcb. Now, another God "HarryM1BYT" shows a picture of a different resistor marked as one of the" failers" to what FrenchMike shows in his picture, unless I'm looking at it wrong, but does anyone know what type the other resistors are and what size they are in that area on the board, under the blob? and what particular size they are, ohm, wattage and physical size etc, or doesn't it matter? if a reading can't be found with a multimeter (i just bought a new one, and both my old one and new one don't show any readings, as if they are open circuit, so how do we know what to replace them with?! i'm not a big electrical wizzard, in fact i've never tackled anything as small and fiddly as these resistors) I've just ordered a table magnifier in the hope of doing these myself.... Even "if", by some miracle I get them fixed, I'll still be worried about putting it back on the car in case it blows again! I've attached a couple of pictures of the bought pcb (first one to snuff it) which seems to show one of the offending resistors looking suspect and the pcb from the known good one (well, was a good one...) Showing the charred area around the right hand capacitor where the gum was. Any pointers and/ or ideas would be gratefully received. Thank you very much!

Yes, silly me, I meant to say pin 3 of the 6pin plug, I use this to activate it via the gsm. I wouldn't think there would be anything wrong with the fan, pump and glowpin, as it would be a coincidence to have the same fault on two different burners, but of course it can't be ruled out, I would suspect the fuel pump wiring, but not too sure how to check it. The batteries on both cars are very healthy, showing over 12.5 volts. I'll try your test when I get chance, thank you for that. What would you advise on resistors there, as they look pretty fried on the second pcb? Thank you very much. Paul |
