Read the stickied water ingress thread at the top of the page from start to finish, just because the drain under the battery is working water can still enter the car through the pollen filter housing if it has not been sealed correctly. Other places are through the window regulator panel you will notice the sill being wet after rain.

You will get a better response if you move the post to the Mk3 section no estates in the first gen.

Door lock on its last legs probably especially its original, they will all fail eventually with cracked solder joints, if you haven't addressed the the water ingress points with corrective action you will get water in the car eventually and subsequent electrical issues related to same, these cars all leak not a matter of if but when, have a good read of the thread stickied at the top. Door locks can be got on ebay but some are of dubious quality pays your money and take your choice in that regard.

+1 on Ken above, look in up in Bosch, Valeo or other decent brand for each application and then compare part numbers, mounting, output etc

Probably build up of crud in the indicator switch contacts, maybe try some electrical contact cleaner, google the issue with the Passat B5.5 you might get some more hits.

Have you ever changed the gearbox oil? That would be a starting point (make sure you can undo the filler before you drain it! they are usually hex key type plugs possibly 17mm), will probably take approx 3 litres fill slowly till it starts to come back out the the hole (car level), see a Skoda or VW dealer for the correct spec oil and capacity, its not expensive. Has the clutch been replaced? Clutch Slave, Master cylinder? Not sure if its cable shift or rods on the Superb mine is auto, there could be a wear issue with them. Get on to ERWIN and pay for an hours access €7 you can download all the manuals in that time.

Jamie you might be better off looking in the Passat B5.5 forums there is tumbleweeds blowing through here, use a multi meter to check power and continuity, It's either: - the fuse - the resistor - the motor - the switch - the wiring in between those parts.

'Water Ingress Problem'........SOLVED! - Skoda Superb Mk I - BRISKODA As a new owner read this thread cover to cover and check all the possible water entry points and repair them asap, you will have cheap reliable motoring. S0054190020-Maintenance.pdf

Mine just broke the 400,000 km mark during the week, its a 2005 1.9Tdi AVF 130 Auto Elegance top Irish spec car, I have owned it since 2012 and put 250,000 km of those on it, though a lot less per week in the last year with covid lockdowns! Its had the usual water ingress issues, door locks replaced, rebuilt the alternator, a couple of cv joints each side, shocks all round, full suspension arms up front, multiple tie rod ends, heater core leaking which was a dash out job to replace not difficult just time consuming and help needed to do it. I have had the egr and intake off to clean them out but everything on the engine is still original. Reverse started slipping around the 200k mark and just after I had replaced the fluid, so I have lived with it that way since and not changed the fluid since, just careful where i park avoiding having to reverse up inclines etc, I think its the reverse drum issue but i am not spending 1500 to fix it and will drive it till its unusable, all forward gear changes are smooth and no issues. Used car prices are going up here with the import tax changes following Brexit so I think I will run it on till till its demise, with their weak points addressed and the 1.9tdi 130 engine they will go a long time, considering it is almost a 30 year old design originating with the B5 Passat in the 90s . I know a lot of the old heads on here have moved on to greener pastures but who else has a high mileage superb still working away daily?

As above fill slowly till it starts to come back out the filler hole, make sure the car is level, as these cars go it is a cheap fix for piece of mind, the output shafts on the gearbox can leak at the seals, if you use the search function it will throw up some threads.

Definitely worth doing if never done should help the shifts especially when cold, MAKE SURE you can open the filler plug before draining should be hex possibly a 17mm for both plugs, use the correct oil from Skoda/VW, they will be able to give you the capacity figure, make sure the car is level when you are draining/filling and add the oil slowly until it starts to come out the filler. The clutch uses brake fluid and is unrelated, I would leave the clutch to a professional unless you have the skills they are not easy to bleed and generally dont need work unless there is air in the system or the clutch master is faulty. Clutch wear is dependent on driving style, but should last longer than that unless there is a parts failure.

'Water Ingress Problem'........SOLVED! - Skoda Superb Mk I - BRISKODA +1 for jimbof's call read this from start to finish my money is on corrosion in the wiring, convenience module soaked in water under the carpet

Passat from 1996-2005 B5/B5.5 should fit cross check the part numbers.

Try banging the door near the lock while pressing the lock/unlock button it might be enough open it, if you do get it open disconnect the electrical plug in the going through the rubber bellows from the B pillar to the door, this will alllow you to lock/unlock manually until you have a chance to replace the lock mechanism, they are available on ebay they are common problem cracked solder joints.

Nice job, you really like a toasty seat!

Make sure you fix all the areas of water ingress properly or all your hard work will will be wasted, there should be lots of these in junk yards these days for parts, not sure that you will be able to get the value out of 300hp as even with the best original engines 130 AWX, AVF they are a cruiser not a car that handles well on the twisty stuff because of their size and nose heavy weight distribution. It looks the part, use the search function to sort out the issues, its quiet in here the last few years but there is great info in the archive.

Read this thread from start to finish, it sounds like a corrosion in wiring issue, could be the drivers door lock, convenience module is under the carpet and will be the first to be affected with the water intrusion.

Steering rack bolts loose? There are a total of 3, Two visible from the top (one under the battery, need to remove) from memory they are 12 sided 10mm bolts (get the right socket and extensions to reach) and one from underneath. Google loose steering rack bolts Passat B5.5 and you will get some hits.

Have you load tested the battery? They can cause issues as they get weaker, get the correct spec battery from a decent manufacturer if it needs replacing. Test the glow plugs if they haven't been done they will need replacing. Test the output of the alternator to make sure it is charging the battery as it should, pay particular attention to the alternator clutch pulley as they usually only last 60-80k miles and will take out the drive belt tensioner if they fail, if the tensioner if hopping a lot a idle that will be a sign its on its way out.

Use the search function there was discussion about these pumps and related issues, very quiet in hear lately and not too many of them left running.

Hi all, I recently took a long road trip after months of local pottering around, the emissions workshop light came on a descent after a long hill pull, on for a few days then cleared itself after so many ignition cycles, came on again on my return journey and I cleared it with the laptop, and it has not reappeared since with local trips. I have checked for charge air leaks other than oil residue on the CCV pipe and the normal oil seep at the EGR nothing out of the ordinary. The exhaust has had bad fumes at idle but not smoking and mpg is down but I had put that down to the short trips, is driving and pulling well through the rev range otherwise. I changed the MAF with a new Pierburg sensor prior to the road trip, no specific issues with the old original Bosch senor other than car is 15+ years old and is coming up on 400,000km and I figured it was getting a bit tired. Has anyone had a blocked/restricted cat on one of these? 2005 1.9Tdi AVF Auto.

Sealing around will work, taking off the metal panel is more time/work, if you seal around the edge you can always remove it later if the window regulator or door locks fail both of which are common faults that require the metal panel to be removed.
