a clean sweep

A faulty exhaust gas recirculation (EGR) valve can cause all sorts of running problems with your vehicle, as you’ll read in our feature starting on page 6. Most of us will only remove and examine an EGR valve when a fault code has appeared, indicating that it’s not operating as intended. However, you can often avoid unnecessary breakdowns by simply cleaning the valves regularly, either in situ or by removing them from the engine. On some engines it is wise to remove the EGR valve at every service to keep it in as clean a condition as possible. If your vehicle is garage-serviced, most likely the mechanics won’t go anywhere near the EGR valve unless you instruct them to clean it – it’s just not part of any service schedule. However,…

lost mot certificate?

Motorists can now replace a lost, stolen or damaged MOT certificate online for free at www.check-mot. service.gov.uk. The service can be used to get duplicate copies of MOT certificates for vehicles, commercials and motorcycles. Initially, the link takes you to the MOT history service, but from there you can input your vehicle’s registration and the 11-digit vehicle logbook (VC5) reference number to view the latest MOT certificate. It is still possible to get a copy of any MOT certificate from your MOT testing station, but this will carry a charge of up to £10.…

mot garage manager guide

The Driver & Vehicle Standards Agency (DVSA) has completely overhauled its advice for MOT managers. The revised Manage Your MOT Centre Guide is now clearer and shorter than before – previously, the information was scattered in a number of different places and it has been reduced in length by 50%. Now all you need to know can be found at www.gov.uk/guidance/ manage-your-mot-centre The guide covers five primary areas, ranging from keeping business info up-to-date, carrying out quality checks, monitoring risk rating and carrying out improvements after a site review.…

exhaust gas recirculation valves

While you should view the exhaust gas recirculation (EGR) valve circuit as a system, modern EGR valves are very deceptive. Despite appearing to be simple, they are precision-made mechatronic components, which means that the majority of modern types combine a mechanical valve, the position of which is monitored – and controlled, in many cases – electronically. However, problems with them are not always highlighted by an engine management light, or fault code, so you might have to undertake manual checks to diagnose an issue. Even if you find that the valve needs replacing, this is not as simple as it appears. Most EGR valves are held to the engine by hard-to-reach bolts and a replacement valve could require diagnostic coding into the engine management system computer (ECU) in order to…

cut-away of an electric egr valve

▶ COILS Activate the magnetic rotor, when the current flows to the coils, responding to the signals from the ECU. ▶ MAGNETIC ROTOR Turns and moves the valve shaft forwards and backwards, adjusting the clearance between the valve and valve seat. ▶ VALVE SPRING Forces the valve to close when no power is supplied. ▶ BUSH Stabilises the valve movement and reduces valve stem wear. ▶ INNER/OUTER SLEEVE 'Maze' sleeve construction prevents harmful materials from contaminating the bush. ▶ VALVE HEAD Controls the flow of gases directly.…
