Hey guys I read your comments and I was having the same problem with my VW Caddy SDI 2006. I understand your frustrations, all cars are a pain especially the older they get. There are a host of issues that I found on my van. I started having issues when my battery was completed dead after not driving the van for a while. I recharged the battery but then I noticed it was hard to start in the mornings. It will take about 7 to 10 attempts to start it and I’ll have to use a power pack as the battery was being drained. Eventually it will start then I get to work or even stop a couple of miles and switch it off back on again it will start first time. I will work for about 8 or 9 hours I get back to my van and it will start straightaway. I go to the shops after work and it will start. I also noticed when I parked the van facing down hill it will start straightaway in the mornings. But it will not start in the mornings when I’m ready to go to work if it was left on a flat driveway over night. So what did I do? I did a basic scan on the ecu with a code reader and noticed there was an issue or code with my ignition switch terminal s and low voltage exceeding the limit. Apparently it’s a common fault for VW’s to have issues with the electrical part of the ignition switch. Went on eBay bought one for about £8 and it was easy to change: have a look on UA-cam how to change ignition switch electrical part. It wasn’t that easy and I had to make my own tools to take it out. If you are not confident doing it ask a friend or take it to a garage. The interesting part was after changing the switch lots of things started working on the van. Like the radio turning off when I remove the key and the immobiliser light was flashing by the driver door. Which I didn’t think of in hindsight could have caused the battery to drain and also cause other electrical issues not even noticeable or visible. So I cleared the fault codes drove it for a day and scanned for fault codes again and there were no fault codes. I was also told by someone who had similar issues with their VW. He said if the battery is weak or the battery generator is not charging the battery very well. It will cause the fuel pump not to work properly. Which causes the issue with having difficulty to start it in the mornings. What he recommended is: If you have a weak battery change it for a new one. Also scan the ecu for fault codes and if there is an electrical fault, fix it. If it can’t be fixed or you can’t find it. As soon as you get home and not driving the car until the following day or for a while. Disconnect one terminal of the battery to stop the battery being drained or the ecu registering the fault. Reconnect the battery when you are ready to start it in the morning. I hope this helps and fixes the issue, it saves expensive cost of being told to change fuel pumps.
This exact thing was happening me. After removing the erg, remapping, non return valves and a new starter nothing was working. Eventually we changed three O-rings on the injectors. That solved the problem. A bad seal was causing poor compression once that van was left up over night
There is a software fault from the factory. As they get older they will not start on the amount of fuel they get to start! However, if you bump start it hot it’ll go straight away, because starter motor is not running?? Anyway it needs to be altered by VW…. I asked my VW garage and they would not do it! So remapped and it starts lively now!!!
Your car comes with a factory map which hinders performance. You can get a remap done from a tuner and turn your caddy into a rocket. You can double the power or more if you have the money and you can turn off useless things like the EGR valve. The map is in your cars computer and tuners can make them better.
hello everyone, VW dealer could not fix it. everything was replaced, fuel filter endine side and tank. fuel pump engine side and tank, all fuel lines checked and blown out with air, fuel tank emtied fresh diesel replaced. still not fixed so i traded in for .......a wait for it......Hyundai
Pokazalo bi grešku, kaže da nije bilo. Mozda ako je Pierburg tandem pumpa ode joj dodatni nepovratni u cijevi povrata, ili zrak ulazi gadno u gorivo pa se vrati u rezervoar. Ili najbanalnije ode kod citac kljuca pa cim upali odma ga gasi

Fuel pump

Mine is doing the same 100kms from home on a dirt road in the bush. How fun! Lol

Hi thanks for the info, I've sold it as no one could fix it. What is remapping?
Please explain what remapping is!! Im having the same problem!!

Das Problem ist, der Diesel läuft zurück in richtung Tank, entweder lange Starten, oder mit Bremsenreiniger helfen zu Starten
Das ist aber nicht Sinn der Sache oder ? 😂
Mines doing exactly same mate did you ever get to bottom of it
No, got rid of it as, everyone I took it to wanted to experiment and I had to pay for their learning and misdiagnosis
injector seals.
Thanks for your input. VW couldn't fix it, so not much hope in them anymore
Its oring from injector
Hi there. Did you find a fix? Got the exact same issue but getting nowhere 😭. Thanks
No, got rid of it as, everyone I took it to wanted to experiment and I had to pay for their learning and misdiagnosis
No sorry no one could fix it after replacing everything that can be replaced. not even VW factory could do it, so sold it as is.
@@PC-Mechanic I replaced the fuel injector seals with the kit x4. Fixed it and sold it, not heard anything since 👍🏻
fuel filter
hello everyone, VW dealer could not fix it. everything was replaced, fuel filter endine side and tank. fuel pump engine side and tank, all fuel lines checked and blown out with air, fuel tank emtied fresh diesel replaced. still not fixed so i traded in for .......a wait for it......Hyundai
Tandem pump
Nah buddy my brother has the same problem I changed the tandem pump fuel pump fuel relay and fuel filter still nothing
Senzor radilice i bregaste
