EGR Valve and Cooler Clogging & Head Gasket Failure

Typical symptoms

•Loud knocking sound on cold start
•Rough idle
•Coolant consumption
•Check engine light with P0401 code

What to inspect before you buy

✓Listen for any unusual rattling when the petrol engine kicks in
✓Check for "mayonnaise" under the oil cap
✓Confirm no white smoke from the exhaust on startup

Rear Brake Disc Corrosion

Due to regenerative braking, the rear discs often don't get "cleaned" by the pads, leading to surface corrosion and pitting that causes MOT failures.

Estimated cost: £200–£400Affects: 2011–2021Often appears around: Age-related

Typical symptoms

•Squealing when braking
•Visible pitting or rust on the disc surface
•Advisory on MOT for "discs pitted"

✓Inspect the rear discs through the alloy wheel spokes

Buying Tips for the 2011 Lexus CT 200h

✓Ask if the EGR valve and cooler have ever been cleaned. If the car shakes on startup, this is a likely culprit.
✓Check the 12V auxiliary battery (located in the boot). If it's original and over 5 years old, it may be near the end of its life.
✓Test the ride quality; the F-Sport models have significantly firmer suspension which may be too harsh for some UK roads.
