I've got a chance to buy a low-miles 1995 E300TE estate with the 'old faithful' 3-litre diesel lump. Have just had a quick look over it with the owner's permission (he wasn't there but we know each other). It's got a little rust on the n/s wing, what a surprise etc, but otherwise it looks OK. The service history is all there and the price is right. I'm very tempted.
The one thing that is worrying me is the floors, which are all wet. The carpets on the boot walls are damp too.
I know it's tough to trace leaks but I was wondering if anybody might have any TE-generic thoughts as to what might be the cause? Looks to have been some attempts to mastic the upper edges of the boot side windows in the past but are there any drain holes and the like that are known for clogging up?
It's not got aircon so won't be a missing pipe from that.
I'm a bit paranoid about this having been stung by a Passat that needed an expensive new comfort ECU as a result of wet floors.
Thanks for any input.

I'm not sure how it gets there, but water can get in up through the floor. Under the carpet you can see the floor is covered in sound deadening - I've seen that crack and water get in and wick up.

Plus sunroofs - they leak and with the vinyl headlining, it can trickle down to the floor through all sorts of routes...

Probably, I'd walk away from that, unless it's cheap and you will use it a lot (to dry it out) and garage it the rest of the time. Or you want it to be a labour of love.

The metalwork under the side windows in the boot can rot and lead to water ingress.

I think if you were to remove the side panel interior trims in the boot you’d find that could be source of water making its way inside.

Having heard from me about this wetness problem the vendor has decided to keep the car, so the decision to buy or not to buy has been taken out of my hands. On one level I'm sorry because that could have been a 'forever car' for us, but on the other I'm relieved because I know from experience what a pain it can be tracing and curing water leaks.
Thanks for the input guys.

Obviously it's academic now but.....

Now I'd hate to give erroneous advice but I have a hazy memory of Ed China (Wheeler Dealers) using a plumbers smoke bomb to find a leak in a car? Or did I imagine it?


Strip the interior seats carpet / soundproofing set the 'bomb' off & see where the smoke exits. If smoke can get through then so can water.

This is for discussion it IS NOT a recommendation!







PS It's better to dry off wet carpet in the car to avoid the danger of shrinkage.

Started getting steamed windows on mine. There's some plastic sheeting in the doors that are meant to keep the damp out that really seen better days.

On my R129 some blind rubber grommets in the floor pan had rotted and fallen out, a 2 min fix.

On my 124 TE, it had a repaired/replaced rear 1/4 panel in it's past.

Water comes in from some rust there, in to the rear foot well, then runs forward in to the front foo twell.

Will get fixed eventually.

Oh, and the electronics are all high up on the bulk head, so no issue like on later cars.

That's very interesting about the electrics. As soon as I felt the damp, our Passat experience kicked in and I went right off it, but if M-B was sensible enough to keep the electric above floor level then maybe it's worth pursuing the guy a bit more. Thank you for that.

I'm presuming the '95 300TE diesel would be the multivalve one?

After '93 these would be badged "E300" rather than 300TD. The "T" disappeared with the facelift.



Wouldn't an E320 be a sweeter drive? The diesel may do a million miles but you'll nod off by the time it reaches 60 and it's rough compared to the petrol six.

I rather enjoy rumbly old diesels!

You’re only realistically going to get 400,000 miles from an E320. Whereas YouTube will provide examples of the diesels closing in on 1,000,000. You need to think long term.

Exactly sir! Armageddon may be near, and if it arrives I would like to be behind the wheel of the automotive equivalent of a cockroach.

Check does leaves under the bonnet by the firewall that could block drain tubes and also blow out the sunroof and fuel filler drain as they could all trap water.
If it's an a/c car, evaporator drains will also clog.

No AC on this car so no problems there.

Again it's academic but from memory there are drain holes that you can rod with media cable or flexible but non kinking wire, access is under the roof rails towards the boot.

It didn't completely resolve the damp carpets in the boot of my TE but improved it immeasurably although on cold mornings the windows would still be covered in condensation.

It may not be academic. Finding out about the non-vulnerable electrics has rekindled my interest in it and I may still be in with a shout. There can't be many of these left with only 120k validated miles.

Approx how much is your friend asking for it?
