Known as the engine over-boost condition, P0234 is caused when the engine control module finds out that the signals from the intake boost pressure sensor are above the prescribed limits by 4 psi for more than 5 seconds.  Mostly occurring in VW Golf, P0234 in VW Golf 2.0 TDI can be treated from experienced and trained mechanics only. As there are several components in a car, there is always a possibility that some of these components can malfunction. To ensure that your car has P0234 and not any other problem, look out for these indications mentioned below:  Illuminated check engine light If your car has P0234, then your check engine light would get lightened up and the code ‘P0234’ would be set in the memory of the ECM.  Failing gaskets  When a car suffers from P0234 or the engine over-boost condition, there are high chances of failure of gaskets. If such incidences occur regularly, it might be a case of P0234 and the best course of action wou

If your car has excessive exhaust gas recirculation flow, that is, P0402 then chances are your car is giving you a lot of trouble. It refers to a condition in which the EGR valve passes excessive recirculated exhaust gases into the intake manifold.  Such problems arise in several cars, such as in the VW Tiguan and Volvo S70. If there are chances of P0402 in VW Tiguan , it is better to get consultations from trained and experienced mechanics. The causes of P0402 can vary from the EGR getting stuck to the loosening of the EGR valve, while its symptoms can vary from the illumination of the ‘check engine light’ to the rough running of the engine. Here are a few things you can do to cure your car of P0402:  Replacing EGR valve  Most of the P0402 cases arise due to the jamming of the EGR valve. Hence, it is better to replace this valve.  Replacing broken catalyst in the exhaust  When there is a broken catalyst in the exhaust, chances are it would give
