Hi All,

I'm hoping you can help with some ideas as to what may have caused some fairly major problems on my 2009 E87 118d.

Got in the car this afternoon after having driven it this morning with no issues, started it up and got the full Christmas tree effect. Basically I've got the following problems:

No ABS, heavy steering (still some assistance), no airbags, no speedo, onboard computer all over the place, fuel gauge moving all over the place, indicators not cancelling, steering lock not engaging when taking the key out, mileage counter not increasing.

Being a 2009 model, I wouldn't have thought the PDC water issue would cause it, but I'm going to check in daylight. PDC is actually still working as well. Anywhere else where water could collect and affect things?

Is there something else that could cause this whole array of problems in one go? No faults on the car this morning, but all this lot this afternoon.

Cheers

Battery could cause that, do you know how old yours is?

Cheers. I can't be certain, but I'm fairly sure it's on it's original battery.
To be honest, I know it's been suffering slightly with charge in the recent cold weather due to the tell-tale signs of the headlights not coming on when unlocking etc, but this was after an hour's thrash down the M40 with the alternator doing it's job well. The multimeter this afternoon said the car's running at a healthy 14-14.5 v when idling so would the battery still cause this?

Probably the PDC, get it out of it's pond tomorrow and you might even be able to salvage it.

Water in the comm's bus in my opinion, swimming PDC is always favourite. Act fast and you might save yourself a bill.

I'd check the PDC if I were you. Don't think it being a 2009 will make a difference would it? I thought the PDC water problem could happen to any age car.

 

[tcm1106]

PDC checked this morning. Dry as a bone down there. Good news that's it dry, bad news that I now have no idea...

You could try disconnecting the battery for an hour or so to reset the system.

 

[tcm1106]

No harm in trying that...

Don't fully shut the hatch down or you will have to drop the rear seat down and crawl through to open it again.

Haha I've just learnt this the hard way...

Oops.

 

[tcm1106]

Right. The battery has been disconnected for over an hour, but still no change after I've just reconnected.

Not good...

Have you got a fault code reader? If so check codes on instrument cluster and check junction box for fault codes.

Unfortunately not. It'll be packed off to autotechnik in Lutterworth this week I think.

What's the junction box?

 

[ste815l]

Junction box is basically the brains of the electric side of the car. Like a motherboard on a computer if you no what I mean.

 

[tcm1106]

So it seems it's the ABS control unit.
Blocked drainage channel on the left side of the bonnet has probably caused it to back up with water in the heavy rain and cooked the unit.
Whoopy doo.
