My 99 VW Diesel Beetle has become very difficult to start first thing in the morning even though the weather is still nice-60-70 degrees. It takes about 5 gggrerers before it lights off but starts fine the rest of the day.
Here is what I have already done....Replaced battery no change. Had starter motor checked-no problem there. Added fuel additive/cleaner no change.
You may need to have your glow plugs replaced, also, you may need a fuel system clean. You can form carbon deposits on the head of your injectors overtime especially with use of diesel that has a higher water content. I would check into a basic tune up with replacing your glow plugs.

Hi Peggy -
If you have not had the fuel filter replaced recently - that is likely your problem. There is a drain plug on the bottom of the filter that likes to brake off over time and cause a small leak where air gets into the fuel system. The air makes it difficult to start and than once its runing it will normally be okay. Eventually the leak will get bad enough that it won't start at all.
Its a big gray canister on the passenger side of the engine compartment towards the front. reach your hand underneath it - if its wet, that's your problem.
If not check all the fuses in the box on top of your battery as well as the terminals on that fuse holder as they are known to melt and cause all sorts of problems.
If you had a problem with your glow plugs it would likely set a fault code. If you don't have a check engine light on I would suspect that is not it. These cars are also know for getting clogged intakes and that may be part of your problem. If it isn't a fuse or the filter you're gonna need to get it into a shop that knows the TDIs to get it handled before it leaves you stranded somewhere.

Good afternoon Peggy- You may want to have the glow plugs and/or glow plug control checked. Diesel cold-start problems are usually a result of one or both of these parts not operating correctly. Cleaners or cetane enhancers will have no effect. Hope this helps. Super Girls Auto.

My first suggestion is for you to take it to a qualified mechanic that knows Diesel VW's and check the "Glow Plug." This is usually the best place to start..you*ve done the due diligence of the fuel cleaner,starter & battery. If you are in an area with cold weather in the winter, make sure you get your fuel winterized, you*ll find it runs better and is expected with these diesel running vehicles.
