2013 LR2 code P0299
Hi! New this forum, but I’ve read several posts to help with a problem we had last week concerning our Fuel Pump Regulator. My husband replaced that. We have a 2013 LR2 with 77K
Now this week- my SUV isn’t switching into gears correctly. The RPMs are going higher than normal and it’s slowly switching into the next gear. The code read P0299... any thoughts on what the problem is, if we can fix it ourselves, etc. Any help would be greatly appreciated!

P0299 code definition
P0299 is a generic OBD-II diagnostic trouble code indicating an underboost condition.
What the P0299 code means
The P0299 code indicates that the Turbo or Supercharger "A" has excessively low output. The ECU looks for a specific range of boost and when the low boost is detected by the ECU, it sets a P0299 code.
This code will illuminate a Check Engine Light on the dashboard and may put the vehicle in limp mode. The limp mode is to prevent further damage to the vehicle and will remain until the code is cleared or repaired.
What causes the P0299 code?
Mistakes can be made if all steps are not followed in the proper order are are not completed at all. P0299 can have a wide variety of symptoms and causes. Following the diagnostic steps properly and in the right order is important for accurate diagnosis.
How serious is the P0299 code?
The presence of the P0299 code can point to some rather serious mechanical failures, especially if left unaddressed. If any mechanical noise or drivability concerns are present, then the vehicle should be repaired as soon as possible. If a turbo charger unit fails and the vehicle is driven it can result in costly engine damage.
What repairs can fix the P0299 code?
When a turbocharger fails it can cause a piece of the turbine to become sucked into the engine. If a sudden loss of power is observed along with a mechanical noise stop the vehicle in a safe location immediately.

What causes the P0299 code?
- Faulty turbo or supercharger
- Low oil pressure in the engine
- Fault in the EGR system
- Air or intake leak or restriction
- Faulty boost pressure sensor
- Check Engine Light is illuminated
- Some vehicles may go into a limp mode
- Lack of engine power
- Mechanical noise (failing turbo / supercharger)
- A mechanic will begin by hooking up a scan tool into the vehicle's OBD-II port and checking for any codes present.
- The technician will note all freeze frame data, which will have information about what conditions the vehicle was under when the code was set.
- The codes will then be cleared and a test drive performed.
- Next, a visual inspection will be performed of the turbo / supercharger system, intake system, EGR system, and any other associated systems.
- After, the scan tools will used to check for proper boost pressure readings.
- All mechanical systems will be inspected such as the turbo or supercharger itself, oil pressure and the intake system for leaks or restrictions.

Had same code and loss of power on 2014 LR2 with 53k miles. Turbo under-boost - took to dealer - covered by CPO warranty - replaced turbo & oil change - another reason to use Land Rover filters, recommended oil per owners manual & strict adherence to the oil maintenance schedule - no Jiffy Lube - lack of proper oil viscosity/inferior grade & poor filtration will cause turbo to fail - without warranty was looking at a $5500 Christmas gift - oil change not covered

Ok I'm curious. Originally replaced the turbo around 30k, now at 65k miles I'm getting p0299 and low fuel pressure alerts. Seems excessive to replace a turbo every 30k. This time around there is minimal noise associated, only notice a lack of power under load going uphill ect. First time it's rattled and limped. I'm of course out of warranty this time, curious if anyone has creative thoughts or know how long the first replacement may be covered?
Appreciate the insight!

The thing about these turbos is that the underboost condition is caused by an exhaust leak at the exhaust manifold flange that is bolted into the engine block. Usually you can see carbon build up which will look black and when this happens not enough pressure is building up in the exhaust to spin the turbo correctly resulting in the underboost.
