MrT Posted April 8, 2006 Report Posted April 8, 2006 On holiday this week with the car very heavily loaded the car engine sounded rough and the engine management warning light came on. On examining it with VAG-COM I got the following faults: Control Module Part Number: 022 906 032 Q Component and/or Version: MOTRONIC ME7.1 G 0011 Software Coding: 00033 Work Shop Code: WSC 000202 Faults Found:16684 - Random/Multiple Cylinder Misfire Detected P0300 - 35-00 - -16685 - Cylinder 1 Misfire Detected P0301 - 35-00 - - If I clear the faults, exactly the same faults re-appear, and cylinder 1 is the only one specifically mentioned. Has anyone had this before and what is there usually a simple cause? My first thoughts were HT Leads and spark plugs. Now I used to be a competent car mechanic 30 years ago in the days of points and distributors but I could not even find anything looking like HT leads on the engine. Now they must either be down the back, under some cover (not the plastic engine top cover) or have changed beyond all recognition. All I could find were six plastic pots filled with epoxy on top of each cylinder with four wires going to each. I thought these might be injectors but there are no pipes near them. I also found an air con fault: Control Module Part Number: 7M5 907 040 D Component and/or Version: CLIMATRONIC MPV GP 0003 Software Coding: 00030 Work Shop Code: WSC 000201 Fault Found:00792 - A/C Pressure Switch (F129) 35-00 - - I somehow think this is going to be expensive. ;) Quote
Guest marcusheawood Posted April 8, 2006 Report Posted April 8, 2006 ...I think you'll find that the six epoxy pots are actually individual ignition coils, it is most likely that the coil on no.1 cylinder has developed a fault and will need to be replaced. Although it could also be the sparkplug beneath of course. The aircon issue may go away with a reboot, it also may indicate that the system pressure is low and needs a top-up, which is common after the winter here. Quote
johnb80 Posted April 8, 2006 Report Posted April 8, 2006 Remove coil pack from No.1 and examine it closely, often you will see a crack on the failed coil pack. Scrape along the crack to remove any carbon traces, degrease it, put it in the oven at around 100 degC for a hour or so to make sure it's dry and then fill the crack with epoxy resin such as araldite. Did this on my mates gold 18 months ago and it's been fine ever since. Regards - John Quote
MrT Posted April 8, 2006 Author Report Posted April 8, 2006 How do these coil packs remove from the spark plugs? I tried pulling reasonably hard to no avail and did not pull very hard as I do not want to risk damaging the pack in case it is not the fault. Quote
MrT Posted April 8, 2006 Author Report Posted April 8, 2006 The coil pack did come off and it was very wobbly. Swapped coil packs and the fault moved cylinder. Took the coil pack off again and it split into two pieces. I'll have to order another one. Quote
johnb80 Posted April 8, 2006 Report Posted April 8, 2006 GSF (German Swedish and French) will have them at better prices than main dealer. Quote
MrT Posted April 8, 2006 Author Report Posted April 8, 2006 I have just read a very interesting article on the particular coil pack I have. In the USA VW recalled their cars because this particular version of coil pack was found to be faulty in manufacture. Obviously Ford in the UK did not bother and mine is identical in part number to the faulty version. Coil Pack Discussion More Coil Pack Discussions Quote
mumof4 Posted April 8, 2006 Report Posted April 8, 2006 Id get in touch with ford and tell them what you have found out and if they intend to do anything about it..if not then do the same with VW. Quote
Dally Posted April 9, 2006 Report Posted April 9, 2006 Id get in touch with ford and tell them what you have found out and if they intend to do anything about it..if not then do the same with VW. Been there and done it. Ford don't give a sh.t. Since I bought my v6, I have had a random misfire on acceleration - happens once a month may be but doesn't show up as a fault. I also get a little vibration and harshness at around 1100 rpm - a local vw specialist (C&R enterprises) told me to change all 6 plugs and all 6 coil packs. I took all this information and the USA recall reports to Ford but they just did not care.I gave up in 2004 and have put up with it since then.I did think about changing them last month when it had it's 30,000 mile service - I thought the plugs would be changed in the service and I'd cough up the additional Quote
MrT Posted April 9, 2006 Author Report Posted April 9, 2006 I have checked out the rest of the coils and they appear to be OK but I was wondering if it is worth replacing the lot as the batch on the Galaxy are all those that VW considered should be recalled. If one has just gone, are the rest likely to follow suit in the near future? Two of the wiring plugs that fit to the coils retaining clips are cracked from where I had difficulty in separating them from the coils, they still hold the plugs securely but the clip part that you move to release them had come away so I now need to slide a thin piece of metal in to release them. I doubt that the wiring plugs can be replaced without buying a new ignition loom, not a problem for me, but I reckon when the car has its next service where the spark plugs need replacing, the garage will break the wiring plugs when trying to remove them from the coils. I am still on the original spark plugs at nearly 5 years old and they have clearly never been removed (or the coils). They look like miniature motorbike plugs from above. I have checked my previous service bills and have never been charged for spark plugs. Quote

MrT Posted April 13, 2006 Author Report Posted April 13, 2006 Put a new plug coil on to replace the broken one and boy what a difference and I don't mean to when it was running on 5 cylinders, but to when I thought it was running on six before. The performance difference is amazing, I must just have got used to the lack of power. Clearly the engine management system only picks it up when it is virtually dead or dying. The point where is failed is different on the replacement so I might as well replace the other five before they totally fail. Quote
johnb80 Posted April 13, 2006 Report Posted April 13, 2006 Glad you got it sorted, Galaxy forum 1, Fraud dealers 0 :o Regards - JB Quote
Dally Posted April 14, 2006 Report Posted April 14, 2006 Denis, You're right - lifes too short, just enjoy the rest of what the v6 gives. MrT, Just out of curiosity, what is your build year and month? and how much did you get your replacement coil for? Cheers Quote
MrT Posted April 14, 2006 Author Report Posted April 14, 2006 It was built in June 2001 and I paid Quote
