Diesel engine light

HI my check engine light came on. I was told it might be a plug that heats the oil. So what are they talking about and is this a costly problem?

I don't believe they meant oil. There is a "glow plug" circuit that is common source of problems for many owners. One or more of the glowplugs need to be replaced. Do not mix, and match the different brands of glow plugs. There are 2 manufacturers...Beru, and Bosch..., they must replaced with the same manufacturers product, no exception. The other thing that needs to be replaced is the "strip" that feeds power to the glowplugs. There is a specific repair kit at your local Volkswagen dealer. They also have the very best wire repair splices that are specially designed for the diesel cars. I would highly recommend taking the car to your local, best Volkswagen dealer to have the repair made, only because they know NOT to change the glowplug brand. They also have the best wire repair connectors. Additionally, the local, best Volkswagen dealer has one, or perhaps two specially trained diesel specialists. The computer tools that are necessary to completely diagnose your cars' engine trouble are there too. It may be more expensive, but chances are MUCH greater that it will be fixed right, and it won't have to go back again, because it wasn't done completely, or well. By the way, Myra, there is no plug that heats the oil, unless the car is intended for use in extremely cold climate, and this is plug that literally goes into an extension cord that reaches into the house. There are heat "pucks" that are then glued to the side of oil pan to keep the crankcase "sump" warm enough so the starter motor doesn't get overloaded trying to turn the engine with oil in it that has the consistency of honey, molasses, or taffy. Myra, Thank you for you question. I hope my explanation was understandable, and I hope, if you follow my recommendation, the repair is successful for a long, long time.

Hi John, These days most oils are formulated to be used in both petrol and diesel engines but those formulated specifically for diesels should not be mixed. If your talking of a top up I suggest a flush with a good quality chemical and a lub service. If you have had a service carried out and changed the type of oil the same applies. Mixing oils can cause fast sludge build up which can block the filter, oil pump and galleries. These days most oils are designed to run both types of engine, but mixing is neve a good idea. Regards John

Does a toyota hilux surf 1995 diesel have spark plugs and points as in the days of yore??


Diesel engines don't have spark plugs. They use compression and heat to fire the diesel. Most diesel engines have glow plugs which are designed to preheat the combustion chamber to help burn the diesel fuel when you start it up. Hope this helps.

Glow plugs might be on when starter is not engaged. wont cold start. have new g plugs no fuel leaks


That is a self priming system on the 6.0 diesel. It has an electric fuel pump check to see if you have fuel getting to the filter up on top of the engine. If you crank the engine and immediately loosen the upper filter housing or crank the engine over with the cap loose it should spray fuel. If you have fuel spray up on top than you most likely have a computer or injector problem. I did have a 6.0 once that would not start because of a shorted out fuel injector. Also check your engine oil level the injectors in that engine are operated by oil pressure. No oil no start.

DO NOT USE STARTING FLUID of any kind on that engine or any engine with glow plugs. Severe engine damage can and will result from use of starting fluids in diesels with glow plugs or heating grids.

The only exception is if you disable the glow plugs or heating grid before using a starting fluid and even then you need to be certain that you know what you are doing

I have a 2001 Ford F350 Superduty. When it is cold out side it leaks diesel from the fuel filter/water seperator. So far this only happens when it is cold outside. If I plug the truck in it does not do...


Hi,
the diesel system on your vehicle works on a continous 'loop". Tank to engine....engine to tank. The fuel filters and the water separator are very susceptible to the diesel fuel 'clouding" , making the fuel heavier to push around the system. The 'clouding' is actually a type of wax which is normally held in suspension within the body of the fuel and thus is not a problem.

The wax starts to plug up the fuel system, and cause lots of problems. The fuel, being harder to push around the system, takes more pressure to move it. This will result in diesel leaqkage at any and all outlets to atmosphere at the pressure end.

The problem is usually resolved by adding an additive to the fuel tank, or having a water separator with a heater., There are also weap-around heating cables which can be fitted to fuel lines to aleviate the same problem. If your water separator has an automatic dump valve, you might like to check that it is functioning correctly and the water content is not freezing and providing an exit for the diesel fuel.

Good luck.

Check your owners manual for the grade and type of oil. Probably a CD4 15W40. Make sure you use oil specifically designed for diesel engines...just any old oil will not work. Also, stick with one brand; each oil manufacture puts different additives which "flush" out of the engine when a different brand is used. It may take a couple of changes with the same brand, but you should see a decrease in oil comsumption.

Engine Maintainance light on


This could most likely be one of 2 things, 1. if it is your maintainance light, it is probably one of your sensors, possibly the mass air filter sensor, oil pressure sensor, and 2. If it is a diesel engine and its the glow plug light, you would need to replace your glow plug relay because it telling you that the glow plugs are still on when the engine is running, which you should take care of asap before you have to replace the glow plugs themselves.
