Hello!

End----------(Elapsed Time: 04:52, VBatt start/end: 12.5V/12.6V)-----------
Was just wondering if these problems are all related to an electrical issue. Some other weird behaves on the car along with the issues found on the app above are:
  • the clutch pedal is slow on return (never sticks on the bottom tho) - this happened after I've changed the clutch master and slave cylinders (before that was sticky to the point that I had to pull it up with my foot) ;
  • the turn signal sound is randomly engaging although there's no active signal switched on - started happening ever since last year
  • the steering wheel is quite heavy to turn, doesn't feel like a power steering wheel actually at all - this happened after I've changed the steering rack
  • the front wipers randomly not working and sometimes after helping them manually they will recover - started happening ever since last year
  • AC not working at all since last summer
  • problems with the locking system, in particular, the rear right door and the boot door - old problem but getting worse, to the point that I can't open the trunk sometimes.
  • rear washer doesn't work (might be disconnected along with the installation or the pump is broken)
  • lately the engine workshop light intermittently goes on on the dash, seems like when I'm pressing the brakes! Sometimes it goes away on its own after a while but comes back more and more often.

Now I haven't always been to a trusted service and some of the work done to it was made in poorly manner and conditions, but yeah, don't we all look for cheaper ways, but yeah, in the end, it's only gonna do worse. I'd say before all these would start I wanted to invest in suspension as the standard one is just rubbish, also get a fmic and then maybe some map. But when these problems started I realized it would be a poor decision to invest in this car. And right now, I just don't know what to do, I don't know if it's a high-cost problem or a cheap one involving just some connectors, fuse, or wires. So this is the reason I've come here because I need some advice, I'd even start to DIY if possible with books and tutorials. Hopefuly you'll be able to help. Thank you!

Your clutch pedal being slow to return is not an electrical problem. Check the bleeder block on the bulkhead, or remove it entirely.
Replace the hazard switch.
What rack did you change it to? Could be a bad rack.
Wiper linkage likely stiff. Just strip, grease and rebuild.
Check pressures, fans, regas if required.
Your door modules are bad. The scan tells you that. Check your harness between the boot and chassis. It'll be broken.
Same above for the rear washer.
Your brake light switch is bad.

For a 20 year old car the above really isn't a big deal. They're old, you need to work on them. What you have isn't a big deal at all.

These are all jobs that pretty much every MK4 owner has had to sort and a good place to start learning, I'd start at the top and work down...

Check your battery connections - especially the one to the fuses on top of the battery. Invest in a battery terminal cleaning brush - you want nice bare lead.
Check the fuses on top of the battery, even if they look good, pull them and refit to make sure they have good contact
Replace the brake switch on the pedal as that can cause a lot of other seemingly unrelated errors. Not sure if they've updated the part again but there was a revision that you could break simply by installing it "wrong" Use the guide here for info
Replace the faulty door module(s) - you can repair these occasionally depending on the fault - famous for cracked/dry solder joints and some nice lead solder will sort them out
The rear washer hose has probably been leaking onto the rear boot lock and corroded the electrics - only solution is a new latch as the micro-switches aren't accessible (and to re-attach the rear washer hose more permanently)

Once I'd done that I'd re-scan as I suspect you'll lose a few of the other codes too (like the other ABS faults and the data bus)

I'd leave the air flow flaps / HVAC until the end once I'd sorted out all the other issues

Dude what your car needs is a serious big service that shoul dtake care of the engine light coming on with the brakes......
just sortout the little niggles p.e. ebay the lock modules and replace them, bleed the CSC properly actually flush the brake fluid and bleed the lot, it might just be down to old brake fluid the slow return of the pedal (i say this because it reads like the car only got MOT failures sorted out. on the cheap)

Any new shocks with fresh springs will be an improvement over the tired ones, the rear washer problem could be a simple cable that has snapped ( top of the hatch look inside the rubber they like to break there) . AC might just need a a refill... Wipermotor can be replaced with a used one, and check the powersteering is actually filled to the max line, most cars if it is to low it literally won't engage at all.

PS you don't need a FMIC it's the PD150 it has one already....

So all in all your car seems to be in less of a state than you think it is.. i have seen way worse, being fixed and sold at top money.

Hello everyone and sorry for the late reply, I was quite busy lately. Unfortunately, the link you left for the switch installment doesn't have pics at all, I know it's an old post but I really need those pics as well along with the text, maybe you can suggest a different source? Thank you all for the replies guys, hopefully, my car's mot will pass, it's in 2 weeks. Will try to do all I can for now, after that will find time for the rest!

I had every single one of these issues over the years on my 1.9TDI (or Passat B5.5) , and most are straightforward and DIY to fix (well-documented anyway). The only one that's a bitch is the HVAC because it's probably a stripped cog in the flap drive, and that can require dashboard removal. It made my Passat not worth repairing, and was a big issue because it meant no heating in the winter, which is a complete pain because the screen will just mist up.
If the car otherwise runs well then it's worth getting them done as the fixes will probably outlive the car.

Can not help with pics but the design of the brake switch has changed over the years.
it now comes with the plunger retracted and when you fit it in to the housing you need to give it about a quarter turn to release the plunger which then self adjusts to the correct length.
Mine did not come with any instructions and most of the manuals are outdated.
Not easy to explain but is a sort of Mayo net fitting in the housing.

Really odd, the link works for me still ? if you Google "DIY - Installing a new brake light switch (without breaking it!)" it's the first hit and it's on the VW vortex site - someone has kindly PDF'd it too https://lupo3lklub.dk/pdf/bremselyskontakt.pdf But as above - I think they've done away with the awful design so you probably won't have the issue.

Hi again.

I've changed the brake light switch, followed the tutorial and all and it seems like the brake light works fine now if I even had any problems, but after I tested the car the same error is still there:

I've also bought a battery terminal cleaning brush, which I used, but didn't seem to help much. Could it be the battery running out? I remember I had it tested last year with Halfords and they said it's on 75% health. What now?

Don't think a battery would cause it.

Did you clear the codes after replacing it? If you did, then you either got a duff switch, bad wiring, or a bad ABS pump.

One thing to note, the brake light switch and the recirc flap motor share some wiring, and both appear faulty so potentially wiring or just a coincidence. Both on fuse 5, check continuity from fuse 5 terminal to ground. If there is continuity then have a short somewhere.

Hi!
A new problem, my steering wheel makes noises when I turn at low and up to 30mph. I’ve checked the fluid level and it’s fine, but regardless, ever since I’ve changed the steering rack, the turning was heavy. Probably due to the fact they didn’t put the proper fluid I reckon. I’d like to flush the installation using this method:


But I need the low pressure return hose diameter size, to know what connector and hose to buy. Anyone here knows that info? Couldn’t find it on internet. Also have 2 bottles of 1L vw original power steering fluid. Will it be enough?
