You’re likely reading this because you’ve got an Audi with the EA113 TFSI engine, and you want to know how to keep it running in perfect condition. The following are five areas where you must pay close attention to achieving that goal:

1. Belt and chain

Some TFSI owners don’t realize their motors have both belts and chains. The timing belt is on the passenger side of the engine, along with the auxiliary drive belt. But, there’s also a small cam chain on the opposite side.

Chains generally last longer than belts. But, if you’ve got no proof that your engine’s chain and tensioner ever got replaced, it’s time to get the work done. The same applies to your timing belt and related accessories such as the water pump and any pulleys and tensioners.

2. Cam follower

A known weak spot on the EA113 TFSI engine is a Worn Cam Follower. The part itself is inexpensive but should get checked at every service and replaced where necessary.

If you have a worn cam follower, you could end up having damage to your intake cam and the high-pressure fuel pump (HPFP). The design of the cam follower changed on the newer TSI engines (EA888).

3. PCV valve

One part anyone can change themselves in minutes and armed with just a screwdriver is the PCV valve.

They are notorious for getting blocked up with carbon and cause all kinds of running problems. Again, the part itself is inexpensive, and it’ll take you just a few minutes to replace it.

4. Battery

Something that leaves many Audi owners scratching their heads is poor performance from their batteries. Many unsuspecting owners assume they’ve got electrical gremlins or end up changing expensive parts like starter motors and alternators.

The truth is, batteries lose voltage if they don’t get charged properly. Cold weather plus short and infrequent drives can exacerbate the problem. Thankfully, the solution is simple: use a good quality battery charger and top up the charge on your 12v battery monthly.

5. Ignition coils and spark plugs

Lastly, if your Audi lacks power and even misfires sometimes, the chances are high that you’ll need to replace your ignition coils and spark plugs. You should consider replacing the ignition coils whenever you fit new spark plugs for added peace of mind.

Many Audi TFSI owners fit coils designed for an R8 as they operate more efficiently (and are actually cheaper) than the OE ones for the EA113.
