Choosing between the two is dependent on your personal preference and of course your budget. Worn parts will be replaced and the turbo bearings and seals will be replaced with new parts.Ī rebuilt turbo can cost around 400-500$, whereas a new turbo may cost double that. As its new, you will have peace of mind that it should last another 100,000 miles, however you will be paying more than a reconditioned turbocharger.Ī reconditioned turbo is where a specialist will strip the turbocharger to each individual turbo part such as the compressor housing and wheel, turbine housing and wheel, bearings and more. Both will fix the car and be backed up with warranties in case the turbo breaks again, but whats the best solution?Ī brand new turbocharger can be bought fairly cheaply and fitted by yourself or a mechanic. If you have diagnosed that your turbo has broken, you will be thrown into the whether you should invest in a new or reconditioned turbo. Below is an intercooler pipe that was cracked (bottom pipe) on one of my cars, which caused very poor performance from the turbocharger. Overtime this will cause unwanted stress to the turbocharger.Įven the smallest cracks in one of the pipes coming too and from the turbo can cause issues.
Otherwise the turbo will be deprived of fresh oil as its spooling down. Always let the engine idle for a minute or so. After a long drive or aggressive driving, you should never switch the engine straight off. This will cause damage to the blades inside the turbo and eventually wear down the turbo until it breaks. Dust, stones, leaves and other small objects can enter into the turbo via the compressor or turbine inlets. Lack of oil changes can result in a build up of carbon deposits entering the turbocharger. The oil should be changed at every service and as regularly as possible using the best synthetic motor oil where possible.
#HOW TO MAKE TURBO SPOOL LOUDER GTI CRACK#
Pipes leading to the turbo often crack overtime and is fairly common (see below photo).
A turbo uses forced gases to push back into the cylinders and if there is a crack or faulty seal, some of that gas will be lost.
Below are some of the main reasons for turbos to fail: Its important to know the reason why the turbo failed because you may fit a new or refurbished turbo that could fail through an underlying fault. Likewise when you have a blocked DPF, it will often cause the car to go into limp mode or whilst going through regeneration of the DPF, there could be excessive smoke. For example, a faulty EGR can cause excessive exhaust smoke and poor acceleration if blocked. The majority of modern cars with a trip computer will trigger the engine management light, which will usually be matched with another symptom above.īefore you point all fingers at your turbocharger, you will want to ensure that the car has good all round health. If you are noticing your car using more oil, this could be a sign that your turbo is leaking oil and leaking into the manifold. You can tell a lot from exhaust smoke and a faulty turbo will cause excessive exhaust smoke of a range of colors. If you are not feeling the usual power when accelerating, the first thing to check would be the turbo. It may be a loose pipe or the blades failing within the turbo. If you here a “police siren” type of noise that is gradually getting louder, this is a bad sign. Turbocharged cars do make good noises such as spooling or a blow off valve noise but there are also bad noises. Turbos are a great way to improve the performance of yours car, however there are many common turbo problems that you should be wary off before buying a turbocharged car.
