Your EGR Valve is clogged and has to be changed. I have tried removing, cleaning and replacing it, this only lasts from one hour to one week.

The fault code 'P3103 V157 - Intake Manifold Flap' comes up on the diagnostics, and if you look in your fuse box (next to the battery) you will see a blown 10amp fuse. This is a sure sign that your EGR (or Intake Manifold Flap) is stuck.

This unit costs about £235 - £250.
Good luck mate

A good run up the motorway with some injector cleaner does wonders a steady 100kph 60mph will suffice and changing the oxygen sensor is not a bad thing ,have you cleaned the air filter out lately ??

Vw golf se 2002 engine management light has come on whilst driving and was flashing but stopped, also emmissions workshop has come on display, the car seems to have lost power?


You need to have a scan of the engine done There are a number of problems that could cause those symptoms. Ask your repair shop how much they charge for the scan Our shop does them free, some shops charge. Get a copy of the scan results and have them clear the codes. Than ask for quotes on the repairs.

What do the white wires in the harness go to, I cut them off (accedent) and am not sure if I hooked them back right. also the 2 tan ones?


Not familar with american motors but i would hazard a guess and assume they are for the lamba sensor ,now the 2 white wires sre for the heatrer on the sensor so they can be connected anyway around but the 2 tan wires have got me as a lamba sensor uses two different colours for the filament in the sensor a gray and black is normal but it can vary although i have seen two black and two grays on some replacement sensors so just connect them up and if iam correct it should work providing that this is the lamba sensor wires you have cut through ,if iam right and the engine symbol light comes off reverse the two tan wires and clear the fault code and try again

Yellow light on dash, emissions workshop warning


Volkswagen vehicles built after 1996 are equippedwith a system of sensors known as On Board Diagnostics (OBD II). These sensorsmonitor many vital engine functions and help to lower harmful emissions. Whenone of these sensors fails it sends a signal to the engine computer to illuminate the "CheckEngine" light in the dash. To clear this light you will need a diagnosticcode scanner. Scanners range in price from $40 to $120 and are available atmost auto parts stores.

1. Connect the diagnostic code scanner to the vehicle's diagnostic port. Theport will be located in the dash below the heater controls.. 2. Turn the key to the"Run" position, but do not start the engine. 3. Press the button on thescanner that reads "Scan for trouble codes." 4. Wait for the scanner to finishscanning the engine's computer. 5. Press the button on thescanner labeled "Clear all trouble codes." 6. Disconnect the diagnostic codescanner from the vehicle.

Emission workshop warning light


You need the OBD codes checked to be certain of the problem. If engine is running ok with the light on, it may well be an oxygen sensor problem.

Emissions Workshop on display


I had this problem myself and was told it could be one of 3 things

1. ignition coils are on their last legs and would need replacing (there are 4 of them in a VW golf)

2. The throttle housing is knackered and needs replacing as it has caused the motor that powers the accelerator to stop working and

3. The catalytic converter has an excess of carbon stored within it and has caused a defect.

All 3 of these jobs are notoriously expensive. Much to the delight of whoever it is you have gone to see....
