Think I've got water in the ECU, its definately on the cables surrounding it.
Car (V6) started fine this morning but stalled when I arrived at the destination. Would re-start but injector light kept flashing. Felt same as lmabda problems, revs dying, having to catch them. Eventually got worse and now the orange CODE light is on and it wont start.
Bought a towbar (£20 worth having!) and got the car home. Gonna spend the afternoon drying stuff out and finding the leak, there is a lot of water in the car and it seems to be coming from the bulkhead not door shuts.
Have I fried the ECU? Got the starting procedure for the CODE and the 5 figure code....just after a bit of sympathy and advice
The quicker you can get the ECU dry, the better (obviously!). Take it out of the car if you can and open it up to dry it.
As for the source of the leaks, do you have a sunroof? The sunroof drain tubes are meant to be one of the culprits. Aside from that, check the 'pockets' that the bonnet hinges drop in to for debris (leaves) blocking any drain holes.
Went down to a scrap yard near burnley on Saturday. They had a skinny V6 there. If you've fried the ECU they might be worth a call. I'll post their details later as they're at home. I think the car still had doors on it but even so if the ECU in the scrapped one has been subjected to damp as long as you clean any corroded terminals and dry it out before you connected it should be OK. Not sure how the CODE system will react to a different ECU though.
ECU is out and it had a bit of water int there, thankfully its mounted with the wiring to the bottom. The water was mainly under the plastic sheet under the circuit board...its ont top of the fire now drying out. Will get a hair drier to the wiring after a coffeee and fag
Looks like the drain areas near the bonnet hinges may be the culprit but will check under the wiper area. I've poured some water over the window and in each corner, cant see any more leaks. Seems that the water dripped down, onto the ECU cable and entered where it had a couple of holes in the protective shrouding.
NEW TIP..........clean the drainage areas regularly....near the bonnet hinges, rip out the triangular rubber bung, there are two under there.
ECU dried and back in............it started....!!!! Thank ****** for that. Took the car for a spin and toe'd it round a roundabout and there is still water coming in on right handers, gotta be a drain hole so off comes the wiper strip now.
Hi Wrinx, I'm sure someone posted about water coming in near the ECU due to blocked water channels (I think under the black plastic wiper stuff).
Hope the car restarts.
Marlon, you're a star...........I had a lovely little swimming pool just about right for action man and Ken to get friendly in. eek!
Under the wiper motor there is a drainage hole about 40mm in diameter, in a 40-50mm deep recess about the size of a marg tub (mine was full), it drops into the back of the engine and ends in a fishtail kinda shape???
Dunno why, as this makes it easy to clog up!! Mine wasn't helped by the 20mm grommet some kind soul had left in there blocking half of it before the leaves and other crud got in.
Anyway, job done, car working, thanks for your help chaps..........and Marlon, I owe ya a pint wink
I had this problem about 2-3 years ago, which was about 6 months after i had bought the car. Water was actually running down the wiring loom into the ECU. Solution was found via alt.autos.alfa-romeo newsgroup. Water was coming in around the windscreen as it had been poorly replaced just before I bought the car.
The final proof that this was where the water was coming in was to push a wad of paper towels as far as possible into the gap between the top of the dash and the bottom of the windscreen. If they come out wet there's a fair chance that's where the waters getting in.
I had no success in sealing it, the only solution was to get the screen replaced. Autoglass said they tried to get it out without breaking it but no luck. Think new one was around £350 !!.
If this is your problem I suggest if possible you find a cheaper way of getting the screen replaced :-O.
ECU survived but there were some pretty strange problems before I realised what was going on.
Aircon fan turning itself on over-night, therefore mystery flat battery in the morning.
Wipers turning themselves on !
Headlamp washers going in time with the indicators !!
Engine still running with Ignition off and key removed !!!
Oh, and not starting of course.
If your worried about it re occuring might i suggest the plastic bag and elastic band method http://www.alfaowner.com/forum/ubb/icons/icon6.gif Used to work on the old motors with distributors and even stopped me old FS1E from dying in the rain when i was younger
Had same problem on my 155.
The drainage holes under the wiper arms (plastic cover) were blocked.
The footwell was a flooded !! luckily the ECU survived but the heater motor resistor packed up and i only had full speed on the fan.
Hi i had this problem to and i took the cover off and 1 wiper passenger side under that there is another small cover which covers the fan look in the channel your see like a big bath plug hole if it is blocked problem sorted i used a metal coat hanger and a hose with water running water to flush it out it was full of dirt hope it works
Is it a big job to get the plastic cover off? Without going for a look, I'm thinking that the wipers need to come off? My passenger footwell is wet too, so I guess mine needs the same treatment...
Fraid so, not a big job but mark the wiper arm position,especially for the nearside! You will need a T20 bit too :d Don't forget the drain under the wiper motor, you can just slide yer hand under the wiper motor mount to get to it.
Ive had all the wipers and covers off this weekend trying to find out where the water in my car is getting in... no blocked holes i could find, no water except around the heater resistor... wierd, carpets are wet tho.
Still at least i got to de-grease the wiper motor again
