    Hi there DJ



    The throttle body is situated underneath the plastic cover at the top front.

    its only 4 allen key style bolts,you will need to disconnect the plug that sits on it, once you have taken it off use carb cleaner and make sure you open the flap and clean it propely.



    Hopefully fingers crossed this will do the trick

    Dj forgot to mention throttle body situated above exhaust manifold

The engine falters at low speeds


The flashing engine check light means a code is being stored in the computer. You need to have this code read and this will tell you what system is malfunctioning.

My Audi A4 1.9 Tdi is showing an orange light on dashboard a circle with caution sign and arrowa on the side facing up and down.


ASR - Acceleration Skid Control system.
When ASR warning light blinking the system is activated itself for car acceleration skid control.


For today's typical high-torque engines, traction control (ASR) can increase both comfort and safety, particularly when driving on slippery roads or surfaces offering differing levels of grip. Traction control permits smooth starting and acceleration through the full speed range without wheel-spin or fishtailing.

ASR only operates in conjunction with the electronic accelerator (E-gas) and uses components of the anti-lock braking system (ABS). If one wheel suddenly begins to rotate faster than the others (slip), ASR intervenes in the engine management system and reduces power until the wheel stops spinning.
The ASR system represents a further contribution to active safety as it maintains vehicle traction and directional stability throughout the acceleration phase at any speed. In addition, it reduces tyre wear. Activation of the ASR system is indicated by a flashing indicator lamp in the instrument cluster.

The ESP system means the Electronic Stability Program. If the ESP lights on the dashboard permanently the ESP system is faulty. You must access the ESP Electronic Control Unit (ECU) memory for pull out all DTC (Diagnostic Trouble Codes), using diagnostic equipment connected to the data link connector of the car. Then you will be full informed about bad pieces (e.g.: front right wheel abs sensor interrupted, ...). After bad pieces replacement you will be able to erase all faults memored by ESP ECU, in other words reset the ESP system and turn off the warning lamp on dashboard.

No acceleration,audi 1.8t,runs like no boost


It's possible that the diverter valve (DV) has failed. The OEM valve has a plastic diaphragm inside and it can crack. If this happens, the car will leak boost air and will lose power as a result. Go to www.audiworld.com, click on Resources, then Tech, and then go to the engine article about replacing/upgrading the diverter valve - it'll show you where it is and how to do it.
