Terminal corrosion...

Featured Replies

I've got the usual water problem and am grateful for earlier topics on this which have got me as far as sealing the pollen filter and lifting the carpet (n/s front only so far). No buckets of water but plenty of damp and stinking carpet underlay. All cabling looks fine, as does circuit board itself, but some terminals of the two CCM connectors are pretty green. I have photos but am struggling to copy them into this post.

Any advice from electronics savvy members welcomed - mainly, what's the best way to deal with this? Just try to clean it all up as well as possible - or do I need to take the connector block apart or anything? What's the best way to clean these connectors? Is there any product that would help?

When I first set out on this trauma I was just getting a bit of a problem with interior lights and door locks etc. Now it seems the battery is constantly being drained and I am getting incredible sound and light shows when I try to start the engine, which doesn't start at all. I am hoping that a lot of this will clear when I get a decent charged battery back in, but this terminal corrosion doesn't seem enough to be causing all of this. Any ideas on why the battery might be draining (other than that it's dying). It was fine before this other stuff started. The car is a 57 plate 2.0TDI 140 and the battery in there is a Varta, which I imagine wasn't OEM, so is likely to be quite new.

Any ideas welcome...

If your carpet has been wet there is likely to be corrosion on some of the nodes. There's a cluster of red/black wires (about 7 or 8 I think) that control the interior lights, there's a high chance they are corroded inside their rubber cover but that wouldn't explain everything. Some of the wires corrode inside the CCM multiplug connectors themselves, here's a useful link that explains how to remove the CCM wires to check:

Can you hook the car up to Vagcom to check?

You need to cut the green wires back to good copper, however this is not your biggest problem, this is:

The car is a 57 plate 2.0TDI 140

Read up on the premature oil pump failures on these engines, personally I would get shut ASAP, a good MKI Superb is great, however a bad one (2.0 PD140) with problems is just a money pit :thumbdown:

Good advice. When you've spent a fortune fixing VAG's lousy cast-off 2.0 PD engine there will be a big bill around the corner for fixing the DPF. So much for diesel economy.

Replace it with a 1.9 PD AWX. Although I've done a lot of preventative maintenance on my Superb which really annoys me (I thought I'd paid the designers), mine has been almost 100% reliable other than a faulty coolant sender - another VAG stock fault.

The 1.9 PD is an absolute cracker of an engine (I bought this car as a cheap(ish) way of getting an AWX in a big body). Mine pulls like a train and will give 55 mpg on a motorway with the cruise set to an indicated 70 mph. Very few other cars of this size and none of similar cost can match this.

All the later VAG diesel engines have problems - so I'll run the AWX until it drops. VAG as an organisation do not match my expectations as honest traders - so no more money for them.

Cheers all. Don't worry - selling is no1 option after it operates well enough to trade it with the same people who offloaded it onto me. It had electronic problems when I got it home from buying it and they offered to give me a trade in price to take it back! So I've no guilt about them having it back. Luckily it was mended in warranty, and to be fair, it has run brilliantly for me for over 18 months, but I will never trust it now.

Gave Skoda a hard time yesterday because of the warranty repair not lasting and they have promised to consider helping with repair once they have 'diagnosed' it. I'll see what they offer and decide what to do next. Think the CCM might be shot...

Although they will of course just palm it back on to another unsuspecting buyer, so no guilt over the dealer taking it back, just a moral ambiguity. Having said that, I'd probably have to do the same. VAG is the offender in all this for releasing such a pile of 5hite onto the market in the first place :thumbdown:

Yep. You're right Jigger, but hopefully by then it will all be mended and someone will buy a car that has had the leaks properly sealed with real VAG mastic and a new CCM provided by Skoda... Actually, now I've said that I feel like it's a bargain and I might keep it... (not)

Always amazes me how much slagging off these cars get on here.

Bought our 2002 Classic 2.0 petrol for a bargain price last March and bar the ingress issue (Charged £60 to fix by DSB in Bulwell) the car has done nothing but impress.

Totally happy with it.

On the other hand, I've also bought a car that I have loved, but the difference is mine has totally avoidable electronic damage that VAG know all about for which they initially quoted me repair costs starting at £750 minimum and possibly thousands. I also find that my particular model has a tendency for the oil pump to pack up with potentially massive damage as a result.

I'm pleased you've been lucky so far, and if mine was reliable I would also be totally happy with it (and have sung its praises to loads of people before now), but I think I'm entitled to rubbish it as much as I want given my experience. Actually, if you read what people are saying it's really VAG that they are slagging off rather than the cars themselves

Fair comment mate and the reason i posted my comment was that we had 2 Omegas before the Superb and the forum for that are full of people supportive of the car they have and singing the cars praises as it were, this forum is great, its just the one or two disgruntled members here who do nothing but rant at VW/Skoda which gets a bit tedious after a while.

Think we're both singing from the same hymn sheet mate. Cheers
