E88

E88

The BMW E88 is the convertible version of the first-generation BMW 1 Series, produced between 2008 and 2013. Available as the 118d and 120d, the E88 combines enjoyable open-top driving with the efficiency of BMW's diesel engines.

At Bimmer Garage Nottingham, we specialise in BMW diesel vehicles, including the E88, providing expert diagnostics, servicing, timing chain replacement, and engine repairs.

Which Diesel Engines Are Found in the BMW E88?

The E88 was fitted with two main diesel engine families:

BMW M47 (Early Models)

Earlier E88 diesel models use the 2.0-litre M47 engine, known for its durability and strong reliability.

Common maintenance items include:

  • Swirl flap wear (on some versions)

  • EGR valve carbon build-up

  • Turbocharger wear on high-mileage vehicles

With regular servicing, the M47 is capable of covering 200,000 miles or more.

BMW N47 (Later Models)

Later E88 118d and 120d models were fitted with the 2.0-litre N47 engine.

The N47 offers:

  • Better fuel economy

  • Lower emissions

  • Improved performance

However, it is also known for one significant issue—timing chain wear.

Common BMW E88 Diesel Problems

1. Timing Chain Wear (N47)

The N47 engine is well known for timing chain problems.

Symptoms include:

  • Metallic rattling on cold start

  • Noise from the rear of the engine

  • Engine warning light

  • Timing-related fault codes

  • Rough running

Ignoring these symptoms can result in serious engine damage.

2. DPF Problems

The Diesel Particulate Filter (DPF) can become blocked if the vehicle is mainly driven on short journeys.

Typical signs include:

  • DPF warning light

  • Reduced engine performance

  • Limp mode

  • Increased fuel consumption

  • Frequent regeneration

3. EGR Valve Carbon Build-Up

Over time, carbon deposits can affect the EGR valve.

Common symptoms:

  • Poor acceleration

  • Rough idle

  • Increased smoke

  • Engine management light

4. Turbocharger Wear

Turbochargers rely on clean engine oil for lubrication.

Signs of turbo problems include:

  • Whistling noise

  • Loss of power

  • Blue or black exhaust smoke

  • Increased oil consumption

5. Glow Plug Faults

Faulty glow plugs can cause:

  • Difficult cold starting

  • Rough running after start-up

  • Glow plug warning light

  • White exhaust smoke

Recommended Engine Oil

For most BMW E88 diesel models, BMW recommends a fully synthetic 5W-30 engine oil meeting the BMW Longlife-04 (LL-04) specification.

To help protect the timing chain and turbocharger, we recommend changing the oil and filter every:

  • 8,000–10,000 miles, or

  • Once every 12 months

This is often more beneficial than following extended service intervals.

How to Keep Your BMW E88 Reliable

To maximise engine life:

  • Change the engine oil regularly

  • Use BMW-approved oil

  • Allow the DPF to regenerate with occasional motorway journeys

  • Investigate unusual engine noises immediately

  • Service the vehicle on time

  • Diagnose warning lights as soon as they appear

Preventative maintenance is the best way to avoid costly repairs.
