Touran Diesel 2003: Engine light on, black smoke and problems with the filament bulb

Hey guys! I have a few questions about my 2003 diesel VW Touran with 270,111 km mileage. I've been having problems with my car - the engine light comes on, black smoke comes out of the exhaust when accelerating, it takes longer to start when cold, DPF regeneration goes wrong and the filament lamp won't go out. Recently had a really bad spin at the mechanic's and think it's a problem with the pre-glow relay (glow plugs). Has anyone had similar problems and had experience with their mechanic that they can pass on? Would be grateful for any tips!

A 2003 diesel VW Touran is experiencing issues with the engine light, black smoke from the exhaust, delayed cold starts, DPF regeneration failures, and a persistent filament bulb problem. The suspected causes include a blocked DPF and faulty glow plugs or pre-glow relay. A similar case involved resolving these issues through a mechanic, suggesting that addressing the pre-glow relay and DPF could potentially fix the problems.

Hey, I also had a 2006 diesel VW Tiguan. Your symptoms remind me of what went wrong back then. In my case it was the DPF, totally blocked. Then there were the glow plugs that gave up. What a mess, I tell you. I had it done at the garage, luckily they're clever and know what they're doing. So it was also to do with the pre-glow relay, as you suspect, and the DPF. Hope that helps you a bit. Take care!

Hey, thanks for your reply! It really sounds like you've been through it. How much did the fun end up costing you, if you remember? And have there been any other issues that have come up since then?

Hey, of course I remember the costs. I was lucky and the mechanic fixed the problem with the pre-glow relay. It cost €280, but since then it's been fault-free and I've had no more trouble - a real relief! No further problems have arisen so far, so everything seems to be in order. Hope that helps you, buddy! Keep at it and don't let it get you down!

Oh boy, that sounds bearable. I'm relieved that this won't cost a fortune. Good to know there were no other problems. You really helped me out there, buddy! I guess I'll get in touch with my mechanic first and get this ironed out. Thanks for the help! Stay safe and healthy!
